What is the age that kids stay free with parents at the Disney Resorts? I know most hotels its either 17 or 18 depending on the hotels policy! I have not been able to find info on WDW hotels. We haven't decided our exact dates for our 2004 trip yet but there is a possibility my DD may be 17 when our trip begins but turn 18 mid trip! Will we be charged for an extra adult for part of our stay? Not sure I'm ready to admit she's an adult LOL but need to know if Disney will! Thanks for any help!
