Two of my favorites (from experience being a Miami resident and having had serious back surgery):
1. " We don't need a sweater at WDW in December - it never gets cold in Florida, right?"
Answer: Orlando temps drop down to 30's and 40's at night (esp. at Epcot, I don't know why) and while that might be spring to New Yorkers, the added humidity in Fla. makes evenings chilly sometimes for kids & older folks. I personally love it; it's the only time I can wear a sweater up there! LOL
2. Even though I had surgery on my (fill in the blank - back, knee, ankle, etc.) I won't need to rent a wheelchair or an ECV. If they can walk, I can walk!
Ans: Well... yeah, but not all day or fast enough after a few hours, esp. in the summer. Don't be proud & admit you have a problem, before you become one. If people think you're cheating because they see you walking sometimes, get a pass from Guest Services that alerts CMs that your problem is not obvious, but it's there.
