We stayed at the Hyatt as a "last resort" as it were, by buying a cheap deal through Hotwire. We actually only paid $275 a night, which sounds a lot, but I think rooms usually go for $400+. We prefer small boutique hotels and B&Bs but they were sold out across the island. This was an interesting departure from the norm.
Parking was fine, we found the self-park lot easily, guided by the valet guy. Checking in was pleasant and brisk, we were personally introduced to a few of the hotel's features on the way to our room. We even negotiated a good room, with garden access. Speaking of which, the room was wonderful; large, elegantly furnished in "high-end polynesia" meaning lots of mid-toned wood and heavy duty carvings. Walk-in closet, iHome iPod player etc, lots of nice touches. Linens seemed like they were a very high thread count, the bed was a king and pretty much perfect. I would have preferred a view though, but you can't have both that and a door onto the garden ;-)
The hotel is right on the beach, although there isn't much beach to speak of right there, it's tiny and unusable. It's a short quarter mile to the Marriot where a good sandy point is to be found. Nice if you don't mind mingling with lots of other hotel's guests, it's the perfect spot for sunbathing and boogie boarding.
These days we don't spend much time just hanging around the pool, but the Hyatt has to have the best hotel pool I've ever swam in. It's got many sections; a large bulging main section and a powerful waterfall leading to a grotto, with a bar. You can swim under rocks and right through to another torrent and continue through tropical pools to more rocky falls. Very well designed and gorgeous just to hang about. We did our swimming in the evening, in the dark and we pretty much had the pool to ourselves!
The sushi bar and Sonz with the Swans were two wonderful restaurants and Sonz isn't all that pricey, wine-wise (about 2x retail, not bad). Of course drinks and food are 50% more expensive that you'd expect back on the mainland but comparable to other resorts and restaurants.
Other highlights: the penguins, the cranes, the flamingos, the gardens in general, the open-air atrium (fun when it rains!)
Negatives: where is the water slide and what is the point of selling that to adults? Need beach/pool towels in the room on day 1, good when you arrive late and want a swim!
