the swan & dolphin definetly have less kids than other wdw resorts & the beds are very comfortable. theres also a new spa that opened up at the dolphin that offers couples treatments, something special for your special occasion. i would also suggest the garden suites at the boardwalk, kind of expensive but they look divine with their private garden entrance, tub big enough for 2, the mini kitchen, concierge service & lounge, plus all the entertainment of the boardwalk steps away, the boardwalk is also romantic to stroll at night. either of these resorts would keep you close to your wedding ceremony location & would provide easy transportation via boat to mgm & epcot which is nice.
