I have been on that tour. It's well worth it in my opinion. When I was there in Jan. I asked about it and they said they would be making some changes for the 50th to it.. so it should be a bright, new version of it then. But it is a lot of walking! :)
Nope! The fireworks and all that jazz should be going daily starting May 5th. I was there in Jan. last and everyone kept telling me that things would be going more starting in May. As for DCA, I'm not quite sure. The Electrical Light Parade might still only be on for the weekends until after...
Nope he doesn't. I hope he doesn't come over to DL. I think he's more useful at WDW because there is so much little stuff, like parades to remember at different parks. Disneyland gives a more relaxed feel and knowing the two parade times isn't hard.
