The only thing that was the consensus of every family, including ours, is that for the nightly rate, pool and beach chairs should be guaranteed. My guess is that they have enough pool chairs for about 30% of the rooms, faaaar too low and we saw it causing some serious anger and jockeying for pool chairs in a line 20 minutes before the pool opened. We opted to stay out of that nightmare and rent chairs from a private vendor on the beach. The resorts beach chairs must be paid for and sell out days in advance too. Cabanas are stupid expensive, with rates changing constantly depending on their inventory. Not worth it, in my opinion. ($800-$2000 per day, which includes nothing but cabana and some chairs)
If their upgrade to The Napua rooms included guaranteed pool space or chairs, that would make sense. But they don't. Napua is irrelevant in our opinion and simply a quick money grab, not worth it.
They need to figure this out, then they can call themselves a 5-star resort, but until then, they are not. Great for families, bring your running shoes and patience, maybe boxing gloves, if you want pool or beach space!
