Other possibilities:
There's a really nice, quiet lounge - Martha's Vineyard - or the Solarium for places to sit, eat, what have you.
The arcade and gym.
If you have young kids there's the kids club, you could book them in and go for a nice meal nearby at YC, BW or Swan / Dolphin and check out Jellyrolls or Abracadabar on the Boardwalk.
At the Boardwalk there's another lounge that's meant to be early nice - I've not been yet but it's on my to-do list.
Do some resort hopping using the buses. AKL, WL, GF, Poly are all worth a visit if you want to venture further afield.
