Your DD will NOT be alone...believe me! Ok, ready? When I went with my six year old niece, she brought FOUR costumes!
For our Askerhaus Princess breakfast, my niece wore her Jasmine costume,
for Cinderella dinner at GF, she of course wore her Cindy costume, for Chef Mickey's she was Minnie and for our night at
MVMCP she was Belle.
A bit extreme I know, but the trip to Disney was her DREAM and we just couldn't limit her to one costume and it was really worth it in the end...all the princesses were so wonderful with my niece, giving her a little extra special attention and telling her how pretty she looked, ect...she was in all her glory that's for sure! Plus we have awesome pictures of Cindy and mini-Cindy, Jasmine and mini-Jasmine, ect....
I will say though, for the days we were in the park, with the Jasmine costume and at MVMCP, my sister brought a change of clothes along for her too. It was very warm and after while their were complaints of being hot and itchy. Also comfy shoes are still a MUST, even if they don't really "go" with the costume!
