Check In--easy as can be! This took about 5 minutes total time, very very easy.
Room--the cleanest room that I have ever stayed in in Mexico. The room was updated and pretty modern, the view was the ocean, no issues at all-just great!
Pools--very awesome--they had 4 pools, there was a quiet type pool along the right side, there was the obligatory drinking and activity pools in the center and a very decent sunbathing pool along the left side. There was plenty of sun and the hospitality was great.
Food--the food at this Riu was much better than the other Riu's that we have stayed at. The buffet had a great selection of foods each day and every night there was a theme (mexican, italian etc...). We did eat at the steak house one night and it was great but entirely too much food, same with the Brazilian restaurant. The good thing about making reservations at this Riu was that you could make them for the week instead of having to go down each morning for reservations.
Staff--this staff was the best staff we have encountered at any Riu that we have stayed. Every single person was nice, helpful and professional. Absolutely no issues at all with any staff only perfection. It was amazing...
OVERALL--We have a great time, the Riu Cancun was absolutely great, the best Riu resort that we have stayed at yet. From now on and when we stay in Cancun we will be staying at the Riu Cancun. (note: we stayed at the Riu Caribe last year and it was a terrible experience with the hotel and staff--pay the extra $200.00 and stay at the Riu Cancun if you can..trust us on this one!)
