I can try to answer. I stayed 3 night in building a and 3 nights at the private pool bungalow. The rooms in building a are nice but the covered hallway is a little weird and the music is extremely loud until 1am (not an issue if you plan on being out every night). The private pool bungalow is amazing, beautiful room, great access to the pool and quiet at night even though your a few steps from the party. Definitely worth the extra price if you can. I did not stay in the building next to the party pool. That is where all the shared rooms are. Looks like a nice building and some rooms have a view of the party pool so could be nice. I also suspect it would be quieter than building a because the pool party stops at like 10pm and the beach party is closer to building A.

you should book in August. Rates start increasing September onwards and steep hike if you book in November or thereafter. But book in those hotels which refund the amount in case you happen to cancel the trip.
