So I know about the movies at Fort Wilderness, watching the boat parade and Wishes from Fort Wilderness (I'm assuming they still do this), what other free activities/experiences/neat things are there to do around WDW? Our trip this summer will be on an extreme budget, so there isn't going to be money for dinners, things like BBB or PL etc... Just wondering what neat little things there are to do.
Most WDW resorts offer the movies, though check on the location within the resort.
A word of caution: If you try to see Wishes from outside MK, you might not be able hear it. (see below)
As for watching Wishes from Ft. Wilderness, a word of warning on the subject....we did this last year. In the holiday season, a fun thing to do - also free- is to visit the guest displays at Ft.W. After exploring the area though, we tried to go back to WL. Our first thought was to walk back, and a CM advised us strongly against it due to (potentially dangerous) wildlife concerns. He told us to take the shuttle bus, so we waited, and waited and waited for (I think) over half an hour.
So we thought to try seeing Wishes form the beach. It would have been okay, but we could not hear it very well. Some very inconsiderate folks were talking loudly over the whole thing. While you maybe luckier than us, all of the viewing locations outside of MK have the show on low volume. If the folks nearby don't are to hear the show, there isn't much to be done, and this is not the first time we've encountered that problem.
Consider ways to eat off WDW property. WDW TS meals are now in the crazy $$$ category. We used to eat on a budget, then went to making quite a few ADR's, but now we are back to avoiding them. I'm not sure how you are defining "no money for meals" - that could mean everything from living off granola bars from home for a week to just not doing V&A's - but we have found a variety of ways to eat better quality offsite for far less than the cost of a WDW meal. Even if you don't have a car, you can eat in the airport for less than WDW.
If you are flying, consider playing around with dates for lower airfare. While MCO is closest, and the only airport with Magic Express, we can often beat MCO prices (plus get a rental car) for less $$.
Last, consider swapping WDW for Universal Studios.
Ticket prices are similar, but almost everything else can be done for less $.
