We are staying at ASMo. I called today to check on the Dream Maker package. I actually found a way that I save about $200, I believe. However, I don't know if the lady quoted me included tax or not. Plus, there are the "free" things that would be additional savings. So, I think I would save money. However, I'm not sure if I want to change to Walt Disney World Travel vs. Central Reservations. What's the big differences? Can I still cancel or change rooms if I find something else? Do I need to have my vacation paid for in advance?
