I was here for a conference.

Cancun is not my cup of tea, full stop. Prefab resort catering to mass hordes of holiday makers (almost exclusively US), with MacDonalds, Burger kings etc everywhere and all depressingly un-Mexican.
Added to this - huge international Hilton-type faceless hotels are not somewhere I would part with my own cash for.
However given those two dealbreakers, stay at the Hilton in Cancun I did, and it was ok given those limitations.
It's on a good stretch of (man-made) beach with a beautiful aquamarine sea in front of it.
The hotel is huge, seems to operate efficiently. Staff were generally very good with the exception of some silly waitress at reception who attempted to charge me for breakfast (already included in my package) as i was sitting at the wrong table.
Breakfasts were very good.
Food elsewhere in the hotel generally was shockingly bad. Only the grill restaurant near the beach served passable food.

Incredible network of swimming pools and mini-pools was impressive.

So the Hilton was fine in a way really and if you love places like Cancun and staying in monster international hotel chains then I'm sure you'll be happy here. If you don't then you've been warned.

I booked a 3 night stay (May 1-4, 2009) through Continental.com.
Apparently the hotel bookings at Continental.com go through Travelocity.com.
On April 27, 2009 (4 days before my arrival date) I decided to cancel because of the Swine Flu epidemic.
Continental Airlines allowed me to cancel the flight reservation to Cancun without penalty.
I contacted Continental.com who in turn called the Hilton Hotel Cancun and requested that they allow me to cancel my reservation without penalty. The hotel refused.
I then contacted Travelocity.com who in turn called the Hilton Hotel directly and again the Hilton Hotel Cancun refused to allow me to cancel the reservation without penalty.
I asked the hotel person to allow me to re-book for another date wthout penalty. Again the Hilton Hotel Cancun person refused.
I booked the Hilton because I thought that it was a classy and reasonable entity.
The Hotel and their policy is unfair and unreasonable. Management at the hotel should be embarassed by this policy. The Hilton Hotel Cancun should be sensitive to their travelers. The Airlines have ackowledged a Swine Flu epidemic. Hilton Hotel Cancun has not. If this is how Hilton Hotel management acts with this issue. I can't imagine them being reasonable in other customer relations aspects. Beware.

My family and I made our 13th trip to Cancun and our 3rd stay at the Hilton and it was great as always. The Golf Course was in perfect shape. We upgraded to a junior suite which was really outstanding with a beautiful balcony with Jaccuzi. The infinity pool is really spectacular and most importantly the service around the pool was fantastic. A special thanks to Javier and Williams at the pool bar for making our stay even more enjoyable. The Hilton was really busy over the Easter holiday but it is so large that you really don't notice. We had family from Chicago actually move our towels and pool bag from our pool side lounge chairs and claim them for themselves proving that even in paradise there are rude people. We ate at the resort several days and the food was great. We had room service one night and it was completely over the top. We did the Zip Line in Selvetica and I would highly reccomend it. It was probably the best activity we have done in Cancun.

We played golf twice at the Hilton which is great and convinienct. We also played Playa Mujeres and Mayakoba, both are worth the 30 minute drives (in opposite directions. Playa Mujeres and Mayakoba are absolutely beautiful golf courses both in perfect condition. Both are Greg Norman designs and are must plays while in Cancun.

It was a little windy when we were there so the surf was a bit rough but it amazes me when I read the other reviews that say there is no beach. there is sand everywhere. We played catch on the beach and volleyball plenty of beach to enjoy along the very expansive beachfront Hilton.

We stayed at Hilton over Easter week and were very happy with the vacation. We had an ocean-front villa, which was worth the upgrade cost.

Room: The room set-up worked well - spacious, beautiful view, decent size sitting area. Bathroom set-up was okay, but dated - not as luxurious as the common areas. We enjoyed the balcony and the proximity to beach. Bed was very comfortable. I liked the simple decor that matched the view - which was the hero anyway. There was a safe in the room, but not one suited for laptops. The wireless connection didn't quite reach to our room, so had to use the hard connection (provided). I was able to connect to wireless right outside the room, but their set-up only allowed one user to be logged onto our room account at any given time.

Restaurants and Villa Lounge: Nothing too bad, but nothing all that great. We had sandwiches at the pool a couple of days and pizzas one night - both good. Breakfast in the lounge was good - fruit, meat, cheese, and a couple of cooked items. The bacon was really good - I can only imagine the calories in that! Evening hors d'oeuvres were on the low end of mediocre - cheese sticks, onion rings, taquitos. Also had chips and pico de gallo or guacamole each night. The corona and cocktails were a good way to start the evening though!

Location: I liked that you could walk up and down the beach for close to a mile or so in either direction. Water was pretty rough, so not a lot of swimming going on. The hotel is pretty far south - most of the bar/restaurant action was a bus or taxi ride away. Bus was easy, and we weren't indulging in the bar scene - but I don't think I would have liked it if we were going out every night.

Grounds: Lobby seems to have been renovated recently (at least based on some of the less recent pictures). I liked it a lot - tropical, casually elegant. The pool. was beautiful and relaxing, water temp was perfect. It was really hard to get chairs on a couple of days. Not entirely the hotel's fault - people staked out chairs early and then didn't show up for hours. Kind of frustrating - if everyone only took the chairs when they needed them, there wouldn't be a need to hog them unnecessarily!!

We choose Easter weekend because of a big birthday - I have to say while I would stay at the Hilton again, I would definitely not choose that hotel at that same time again. It was really loaded w/ families. Think this contributed to the aforementioned problem w/ chairs - and when we were in line at lounge or working w/ tour desk there always seemed to be someone darting in front of us or hovering over our shoulders as we were trying to transact business. There wasn't anything egregious, it just took a little bit away from the sense of relaxation.

All in all, I would recommend the Hilton - not for landing in the lap of luxury, but for a lovely, casually elegant, tropical break!
