I have never seen any resort employees clean as much as RIU playacar does. WOW. Every single day they were cleaning (soap, water, scrubbing) all the stairs, walkways, windows, pool...
Hands down one of the cleanest resorts you will go to.
Best way to describe this hotel would be a family hotel. We went in March and there was a good range of ages from 20's to young families, to retired. Nothing to crazy, but they ensure everyone is having a fun time.
If you're looking for an affordable, clean, all inclusive hotel. This is probably what you're looking for.
