La Orana,
Thank you for your help. We got a chance to chat with a few folks at The Hilton, Moorea. Everyone told us to opt for The Brando without thinking twice. Hence we have opted for The Brando. Unfortunately, they don't have OWB since we wanted to experience that at least once, but I hope that its natural beauty (since its a private island) will offset everything else.
BTW, I suggest you stay diligent while booking with Pleasant Holidays, in case you are dealing with them. They first offered us an option of The Brando since IC Thalasso's AC was not working. When we informed them that would like to confirm our relocation to The Brando, they informed that there was no availability. I was a little skeptical since this all happened over the weekend. So, I called IC Thalasso directly and they informed that The Brando is available and they confirmed our relocation. Glad that I called the property directly. It is a pretty hot day and sunny day at Moorea (about 95) today and we tried shutting down the AC for a while in the room just to try the experience, boy it was really hot and we were sweating.
Thank you everyone for your thoughts and help.
