Ah.... If GF is on the list then I would recommend it even though I have not stayed there yet, it is still on the list....however I have stayed at the POLY which is on the monorail line and has nice large rooms and very good food options right at the resort and the GF has all that too plus it is just a beautiful resort IMO. Last summer when we were at the POLY we were told we could visit the pool at the GF for a day since the POLY has no hot tub and the GF does....so we spent the afternoon at the big pool that has the slide near the water play area and loved it. We also ate at Gasparillas several times alternating with Captain Cooks and of course we always character dine at 1900 Park Fare for at least one dinner...
I love the lobby at the GF, even my grandkids love the lobby and stairway...and we love the shops....in fact one of the first things I do the first 24 hours on property is hit that Basins and Bath shop and buy a boat load of bath bombs for us !!! We take amazing bath soaks our entire visit at WDW!!!
The other resort I love that you mentioned is Beach Club. I stayed there 2 summer ago and it is a favorite too. THe rooms are big bright with lots of storage and the pool is amazing as the wonderful map from @
NYwdwfan fan displays. BC has Cape May for character dining in the mornings, probably my favorite buffet for breakfast of all the restaurants on property. Beaches and Cream has great bacon cheeseburgers, they have a nice little salon where you can get massages too, the porches are great to sit on and people watch, the nightly movies on the beach are fun for the kids, you are a short short walk away from the International gateway into Epcot, boat rides to HS, Boardwalk and the amazing Flying Fish restaurant across the water and don't forget to walk over to the Dolphin and have either breakfast or a fantastic salad from the Fresh Med restaurant....and they have Mandara Spa over at the Dolphin too which is a nice spa that runs specials and always a treat for me. In other words Beach Club has location location location!
Also have been to Boardwalk twice. Now I like the Boardwalk. Again nice big clean rooms, lots of storage, nice colors, very nice lobby and grounds, varied food options, some quite good, boat rides to EPCOT or HS, or not a far walk, love their pool too, and their quiet pools have excellent hot tubs with powerful jets for sore muscles! The downside to the BWI for me has been you can get really stuck into a room in the south forty area and I don't handle that well...but of all the resorts BWI probably has the nicest CMS working there.
I've stayed twice at POLY and love that place but I would avoid at this time due to construction.
Never stayed at Yacht Club but can't see where that would not be a nice place and it shares alot with the BC, like the pool and porches, easy access to both properites food establishments.
I still want to try the Contemporary too but not too interested in the Bay Lake Tower place...wouldn't pass on it for the right price but not a priority place to try.
SO I vote Grand Floridian and Beach Club second. Have fun with your selection!
