I'm not sure exactly what time of activities you're looking for, but I asked a similar question recently. This is what we're planning on so far:
- Pin trading. I'm going to make lanyards and hopefully get some authentic but cheap pins off of ebay from a reputable seller.
- Penny presses. I'm going to stack quarters and pennies in the mini M&M containers so they're always ready.
- Hidden Mickeys. My boys are old enough to try and actively spot these now, but I'm thinking of getting a guide as well.
- Pirate Cruise. We're not going to do a lot of planned dinners and stuff like that, but I think the boys would enjoy the Pirate Cruise where the kids go off on their own and search for treasure. I was thinking about the Pirates and Pals, but they're not overly into meeting characters, we'd have to go with them, and it would cost a ton more.
Hope that's helpful in some way!
