Arriving on Dec 31st and staying at Saratoga Springs for 3 nights and then one night at Old Key West. I have a waitlist for the last night at Saratoga. Minus the moving it might be nice to stay at Old Key West since we have not seen either resort. Anyhow we drive. Arrival on the 31st could be when we want. We could push it and arrive early. Is it worth it to be at MK that day? I am expecting it to close at some point. My kids are 10 & 7 and experienced WDW goers. Would there be anything to do or will it just be too super crazy? Or will the atmosphere help take the sting out of long waits? What time should we arrive? Would we be better off elsewhere? Other ideas? Thanks!
