We stayed at the Swan last Thanksgiving day and arrived around 4 pm. Never been to Disney Quest but here are some other things you could do without using up a day on your Park Hopper or Plus Option (not sure if you have kids with you so that may influence your decision):
1. If it's warm enough, check out the grotto pool. It is a beautiful pool with slide and waterfalls. You can buy drinks at the pool. It was only 70ish air temp when we were there and the water was cool, but we loved it.
2. Walk the boardwalk area and visit the other resorts on foot, including Yacht & Beach Club, Boardwalk, and Dolphin Resorts. Browse in the resort gift shops. Get a chocolate croissant at the boardwalk bakery.
3. Play mini golf. It is a short walk from the Swan.
4. Plan a nice dinner or late lunch. There are many, many choices of places to eat in all price ranges between the resorts and the boardwalk area restaurants. Again, all a short walk.
5. If you have a car (not sure if the busses go there), visit Downtown Disney. Only will take you 5 minutes to get there. Lots of cool shops and even more places to eat. If you are not with kids, visit Pleasure Island at night.
6. If you don't mind using up a day on your Park Hopper, might as well walk on over or take the water taxi to Epcot or MGM. Epcot is a very relaxing place to walk around and a good way to get your feet wet at Disney. The only disadvantage is that the Future World section of the park will have been open at least an hour before you get there, so there will be lines for some of the major attractions. But you can get by OK using FastPASS.
Good luck!
