warning: I don't have a LOT of spa experience to compare this to. We'd been looking for hot spring…read moreoptions, and this was convenient, although not at all a natural hot spring place. Also very expensive compared to what I'm used to. (like I said, I don't have much spa experience) But it was a very cool place with lots to do. And we did almost all of it, just the spa part, and it took about 3 hours. There are many pools inside and out. The view, of course, it unbeatable. Some of the jets didn't work, which was a little disappointing. There are many rooms/experiences just going from room to room. Some were fun/cool/unique. Some, I thought, were silly and too similar to the room next to it. But you can make up your own mind.
We didn't eat (it was a very nice buffet, but very limited if you're gluten free/dairy free like me) or do massages. And it definitely got increasingly crowded as the day went on. So I suggest AM and weekday. Having so many people around, and waiting for certain things definitely takes the Ahhhh away from the experience.
One complaint, they give you a thick robe and plastic flip flops. For my feet, I absolutely couldn't wear them, it was super painful, even to stand. So I suggest bringing your own water shoes. And it was VERY hot in there for me, so I didn't wear the robe either. I carried it for the first hour, along with the shoes, and then just wore my bathing suit and no shoes (slippery, be careful) and if you want to eat, the robe is required, fyi.
