We just had this cabana for the weekend (sat and sun) and it was well worth it! We brought some beers down and cokes from the club level.. no one said anything.. course it was very busy both days.
The cabana #2 is very near the beach bar, you can see the movies from it, set back just a little from the pool, but on the upper level, so you still see it all! We had it from 8 am til 11 pm and used it for quite a bit of that. Did the parks in the am and pool after lunch. Sunday stayed til almost midnight talking with people in #1. The service was acceptable, as they were slammed. We had a reserve anyway.
I would say that it made the HRH stay better than it would have been without it. On Sat. we sat and watched the College games, going for a dip every once in a while... every guy who came by had to stop to see what the score was... no matter who was playing!
IMHO you can't go wrong with them at HRH... don't know about any of the other hotels.
