I booked and paid for the highest class room, was told when I arrived it was not available for me, and was given a standard room (next to a noisy ice machine!). Most upsetting was that I was told that no refund is possible because I didn't book directly with RIU, and that nothing else could be done. After being informed of this, a key card was shoved into my hands and I was told "go that way" and not even offered help with my luggage. All in all, I've never had a resort or hotel treat me this badly nor did I think it was even possible. So, take this into consideration if you're thinking of staying at the RIU Palace Las Americas during your valuable vacation time.
