I recommend that travelers stay in the city of Cancun instead of the Hotel Zone. This is the best way to experience Cancun and the Radisson offers everything you could need (ex. transportation to the beach, a pool, tennis court, close to good restaurants) for a good price.

The hotel is located in the town cancun and not on the hotel zone. It's a good hotel for 1 night after arrival, but that's it. The rooms are ok and the food aswell, but there is not much in the area.

We stayed here for one night on our way back to the UK from Belize. It is within walking distance of the bus station, just, as long as you have wheeled luggage. Took us maybe 15 minutes at an easy pace, otherwise the taxi fare is about US$4. The hotel was actually more upmarket than I was expecting with free wi-fi internet in the room and smart decor throughout and a reasonably sized pool area which we overlooked from our balcony.
Our tariff didn't include breakfast so we walked out and had a great breakfast at a smart cafe packed with locals about 300m. along the street - turn right out of the entrance - and it occupied a corner spot.
There is a small but interesting Mexican market along Ave. Tulum, behind the fire station, where we picked up some souvenirs at good prices without the hassle of haggling.
This was a good place to unwind after a fairly tiring trip and I'd recommend it if a hotel in the downtown area is what you are looking for.

We chose this hotel primarily based on the price as we were only staying in Cancun one night arriving from London. The hotel is located 'downtown' which is actually quite far from the airport and the hotel zone...and there is not much around it. However our rental car was delivered to the hotel, so we did not have to find a taxi or go anywhere. The room was very spacious and clean, the bathroom had nice toiletries from Asira. There is a swimmingpool, a couple of bars and the staff are friendly. For £48 (without breakfast) is definitely a good alternative to more expensive hotel zone accommodation.
