In the past, we've used non-parks days for a waterpark visit, swimming at our resort and shopping around the Epcot resort area. We have two non-park days in February after our APs expire, and we're planning to do the following:
1. Run a half marathon!
2. Breakfast at Kona
3. Swimming at resort (we're staying at Poly)
4. Boat rental (sea racers - we rented at YC once and loved them - really looking forward to renting at Poly!)
5. Drinks at Trader Sam's
6. Dinner at Jiko - usually only go there when we're staying at AKL, but with a non-park day, we have plenty of time to get there
7. Wishes from the Poly beach
8. Sleep in!
9. More swimming at resort
10. Disney Springs
11. Boathouse for lunch.
I love the idea of a dinner show, but we just did Hoop Dee Doo again earlier this year, and the Poly Luau is not offered on our non-parks days. I prefer Hoop Dee Doo, but either would be fun for someone who hasn't experienced them recently!
