I stayed HRH Club a few years ago and I was a disappointed in the size of the lounge, it was always packed in there inthe mornings and it was hard (if not impossible) to get a table. We had to take breakfast back to our room a few times.
I was also not thrilled about the desserts in the evenings, on a few nights they just had oreos and chips ahoy cookies. Other nights were much better.
We enjoyed our stay, the rooms were great, the views, the pool & cabanas, I really liked the hotel.
I am trying PBH Club in a few weeks, hoping it will be better than HRH Club.
