We have stayed at Dolphins Cove many times over the last say 10 years. The property grounds are very nice. The Pool area was recently re done a couple of years ago and it is very nice now. Two large hot tubs on each end of the pool are great. They have BBQ's available to use through out the property as well as a little miniature golf course that is free to use. They have been putting split systems in the properties so almost all of them have air conditioning at this point.
I attached a couple of pictures of the current pool.
Overall the rooms are average but they are spacious and have full kitchens.
A Couple of things to keep in mind.
There is not daily service to your room. They don't come and change your towels for you or anything. (I think you can add it but it costs more)
There is no washer/dryer in the rooms. They do have on site laundry which is free to use.
Wifi is pretty slow unless you pay for the upgraded Wifi.
If you have a car, to get your parking pass they send you to the kiosk where they will try and pressure you into a time share presentation. Its annoying.
There is a Dennys next door and you can catch the ART bus right around the corner if Disney is back open. IMO, it is to far to walk to and from the Park.
