My DD will turn 10 4 days into our 7 day stay at WDW. The travel agent booked her as a child since she will still be 9 when we check in. She only eats enough to need the childs dining plan, but since we are celebrating her birthday with a dinner at O'Hana's I just know someone will ask her age. I hate to tell her to lie and say it's her 9th birthday. Will they really care about this or does she need to upgrade to an adult plan midway through the trip?
