I am just dying to try out the new hotel but I do remember the glitches that had to be worked out in the first few months of Portofino AND Hard Rock... new employees, new problems.
As much as I'd love to brag about being the first person to be in the room when it opens, I think I'll wait till I hear the reviews before booking the RP. The HRH is a done deal, we know that it's a great hotel, and the RP will only be one month old when you go. It's your call!
