It is an excellent pool, or collection of pools. I think there are 3 or 4 of them. The grotto with the waterfall, large overhang and bridges are wonderful, especially in those hot Florida days where you'd like to be in the pool in a shaded area. You can hang out under the waterfall. It beats the BWV pool by a long shot, and is open all night which beats the SAB for availability.
The Dolphin has I believe 8 restaraunts. We've gotten a rate of $129 per night, which was too good to pass up for some high point value weekend days when first arriving. The sandwich, desert, ice cream shop at the Dophin is great, we'll be walking over there from BCV from time to time. Very nice reasonably priced lunch, great selection. It is a beautiful hotel.
