I had seen that a few other users were successful at getting the Dolphin for such a good price, so I gave it a try and was successful myself!!
Amenities are as follows: Resort, Smoke-free rooms, Fitness center, Pool(s), Restaurant(s), Business center, Self-service laundry, Internet access, Golf nearby, Tennis nearby, Spa services, Children's activities, Accessible for visually impaired, Accessible for hearing impaired, Accessible path of travel, In-room accessibility, Accessible bathroom, Accessible parking, Roll-in shower
There were a couple things I noticed when I was looking at this deal the past few days: Firstly, sometimes it will say that the last person who booked this got the Wyndham Grand Vacation Resort. This is false for this deal and it was throwing me off at first. If you play with the occupancy numbers and put in 4 adults instead of 2 adults / 2 adults & 2 children, the Wyndham will come up instead of the Dolphin and you can tell by the amenity list and the number of tripadvisor reviews.
This is a seriously amazing deal when you're looking at both the regular price for this resort and the price of the surrounding deluxe resorts at Disney.
