We've stayed at the Swan before and we really liked it, nice decor, good facilities, staff were all friendly, can use the buses/boats as normal. I agree the location of the Epcot resorts just can't be beaten in my mind. So nice to be able to just walk to the entrance of Epcot at International Gateway. I think the only reason we'd not return to the Swan is the fact we've usually had free dining on all subsequent trips. Can't remember the room number we had but was nice and quiet and overlooked the wedding pavilion or a wedding area.
I love the Yacht and Beach but our finances wouldn't stretch to it this year either so we've opted to try AKL which came out cheapest of all the deluxe for our dates and has free dining. Only thing I worry about with AKL is the location, but we will try and it and see if it works out!
