I hope your DD gets well soon! And I have 1st hand experience with getting sick at Disney, unfortunately! I was a nail biter my whole life, and we went to Florida for a week in the end of Feb into beginning or March. I bit my nails like there was no tomorrow. So, I got a nasty 4 day stomach flu.

It was the morning that we were supposed to leave, and I woke up and puked. So we had to stay an extra day. Then the next day, we all piled into our car and made the loong 17hr drive home. Thankfully, we didn't hit any traffic, and we left at 4 or 5am, so we actually made the drive home in 14hrs. Ever since that trip, I have been extra careful down there. My mom brings hand sanitizer wipes and I wash my hands extra carefully every chance I get. And I don't touch my nails at all.
