I'll give it a whack...we had our usual Contemporary Resort booked one year and weeks before our arrival, Disney called and offered us the GF, same money....we took it, didn't care at all for the whole resort and concept ... WL just opened and we took a trip over and love it from the start...have had many a stay at WL after that... We booked a stay once at the Poly but they didn't have all the nights we wanted and did our first ( and last ) split stay... First 3 nights at AKL then move to the Poly for 6 more nights....we couldn't get out of the AKL fast enough, though we had a Savannah view room, the whole African vibe, meal offerings, layout, no animal Savannah from our room... Totally too far from anything we wanted our Poly Stay to begin to feel like a Disney vacation we were so used to... We've learned our lesson, book what you know you'll enjoy, no matter the cost...when you travel 1100 miles, I want comfort, ease of travel and amenities we're used to.....our bottom line is location... We prefer the MK area...
Wanted to add, we have no problem doing repeats on resorts... No ambition to try them all but we have done quite a few and have weeded out resorts never to return to and resorts we're quite happy with.... All on property...!
