Beautiful hotel. I've stayed a couple times. Recently renovated and just gorgeous on the inside. Check-in cast members vary on friendliness. If you're lucky and get a good one, politely and energetically ask if any 'no-charge' upgrades are available and you might get lucky. Concierge is wonderful and is occassionally given as a free upgrade.
Best resort area on property for adults IMO. Can't go wrong at Yacht, Beach or Boardwalk. Walking to Epcot is a great perk since Illuminations shows late every night and you can walk over after returning to your hotel from other parks.
Can't comment on Yacht restaurants but Beaches & Cream is great, and you've got the Flying Fish across the lake, as well as Spoodles, both of which are frequently reviewed favorably on the boards.
Downside is that it is a convention hotel, which makes it odd sometimes to be in theme park attire mixing with men in suits and ties.
Lounge recently began serving continental breakfast making it much more convenient than previously.
I think the quiet pool and hot-tub can be romantic if not invaded by noisy kids.
If you want a little romantic hideaway, take a water taxi to the Boardwalk, walk up the stairs to the Lobby of the Inn, take a left, walk down the hallway and out the door at the end of the hall. There, you can descend the staircase into the rose garden. There are many benches. Very secluded beautiful, dimly lit and romantic. They have weddings in this area on some Saturdays. People may be on their balconies however, but even so, this area was pretty quiet the two times I stayed there.
Enjoy! I'll be back at the YC in May! Can't wait!
