Oh to have that problem today (On Spring Break at home)
A non park day...starting at our home resort, SSR.
1. Definitely a spa day, massage with mani/pedicure
2. Put on my walking shoes and stroll around the lake, over the bridge behind Turf Club and then stroll OKW. Take a break at The Gurgling Suitcase and take the boat to DTD to window shop, maybe have lunch, sit and watch the boats, birds, tourists

.
3. Rent a bicycle from the community hall.
4. Take all those classes I always wanted to take at the Community Hall.
5. Take my mug and book, either sit by CP quiet pool or in one of the rockers along the water.
6. My DH would be playing tennis with as many people as he could get to play with him.
7. If we played golf better, we'd find a way to play a round of golf.
8. if I were a pool person, I would go to the main pool and do the activities or just stay at a quiet pool and float

9. Ride the boat to DTD, then get one the next one to OKW or POR. Then have lunch and walk around the other resort.
10. Rent a watermouse at DTD.
11. Walk around SSR and the river, take tons of pictures
12. Heck, what I would really do on a first non park day...get up leisurely, take a morning walk around the lake, read a bit, lunch at the Turf Club and then head over to DTD and window shop/shop until I drop
Need more, my DH and I have gone over all the different things we can do now that we stopped being park commandos. I can get the list from my DH. He's got in his planner and adds to it all the time. It started when we had a almost non park day last summer. Everyone except my DB and his DD, just chilled until dinner. My DH and DDad went to the CR/GF to look at the tennis courts. He lost my DDad (another story) but he ended up doing several things he always wanted to do AFTER he "found" DDad. He started writing other things he'd like to do in WDW.
