The deluxes I have stayed at are the BWI, GF, WL, AKL, and Poly. I'll try to briefly give my opinion of each.
BWI--has a great location with such a short walk to Epcot; I love the room decor and the relaxed but fun feel of the resort; I always feel tranquil and relaxed when I'm there; I would definitely stay there again
GF--this is my favorite WDW resort; I love the ambience and the way the CM's tell you to have a grand day all the time; I also feel that it's a good value, since you get some perks that you must stay in a concierge level room to get at the other resorts (like bathrobes and a stocked mini-bar--stocked with everything, not just alcohol); the rooms are very large; the resort has a lot of nice amenities like the marina, spa, etc.; I felt so pampered the whole time I was there; monorail is so convenient
WL--I stayed here at Christmas time, and the tree in the lobby was gorgeous; the rooms are small for a deluxe; the theming is quite well done, though the woodsy theme isn't necessarily my favorite; felt the transportation was pretty fast, but I prefer the monorail or a walk to get to a park instead of the WL's bus or boat transportation; many kids really enjoy this resort
AKL--this is my second favorite after the GF; I am not an animal lover, so I wasn't prepared to like this resort as much as I did; the theme is amazing; it is incredible to see animals right outside your balcony (if you have a savannah view); the buffet restaurant here is great (Boma); the CM's are very friendly; you really feel like you have escaped stress and everyday life when you're here; bus trips were a little long since the AKL is sort of separated from the other parks except AK; I will definitely stay here again
Poly--this resort is very laid back and friendly; the monorail is great for transportation; the restaurants here are wonderful; the landscaping is gorgeous and relaxing; we had a concierge room with a view of the castle that was amazing (#1512); I did not love the room decor--the colors were a little too muted for me; the concierge staff was incredibly friendly, as was the rest of the Poly staff; you feel like part of the Poly family when you stay here; I would stay here again, but only in concierge
I hope this helps!
