We are planning a trip in July to do Discovery Cove, Seaworld, and maybe Busch Gardens. I am a huge disney fanatic and can not go all the way there and not do something Disney. I am looking for inexpensive activities fun for the kids that are not in the parks as we won't be buying Disney tickets. Already considering: mini golf, Ft Wilderness sing along campfire, shopping at DTD, ESPN club, and maybe a character meal. The meal is more than we want to spend, but considering it. Just FYI, we have a November trip planned for our Disney fix. I wouldn't give that up all together. My kids have been fortunate to go many times already, so missing things is not a big deal. So, what is your favorite budget non-park activity?

Kids were 11, 8 & 5 so similar in age to yours.
We've found that Poly is one of the harder resort parking lots to park at. I would say about 1/2 the time we have gone there, they have asked us to pull away slowly so they could note our lic. plate #. And many times they will consult their list of ADRs to see if you are on there. I think they have to do this because people will park at Poly and then ride Monorail to MK.
