The Dolphin is a 4 1/2 star hotel with a large beautiful lobby. It has a "Grotto" pool with a water fall and a cool slide. The pool is very large (actually 3 separate pools plus a baby pool) and there is also a beach area with hammocks and a play area. The Dolphin has an arcade, ice cream parlor, and laundry facilities. The Dolphin and its neighbor the Swan have several restaurants from a 24-hour cafeteria to one of the best steakhouses in Florida. There's also a meal with Disney Characters.
The best part about the Dolphin is LOCATION! You can walk to Epcot and take a short boat ride to MGM. We don't even rent a car when we stay there. The Dolphin is next to the Beach Club/Yacht Club resort, which has rooms starting at around $300/night, and it's right across from Disney's Boardwalk, a great spot a night with a carnival type atmosphere.
The "rack rate" for a standard room at the Dolphin is $325, and most of us are thrilled to get a discounted room at $149. For $69 a night, you are getting a GREAT deal! (I assume this is from Priceline.)
