You might be careful about booking too many character meals though. When I took my 8 y/o GD this past January I had CRT breakfast (for the Princesses), CP dinner(for Pooh and Friends), Chef Mickey's dinner(for Mickey, Goofy, Chip & Dale), and Donald's Breakastosaurus for (Donald & friends). I didn't realize Donald is in the lobby at Chef Mickey's, but it was a good thing. My GD enjoyed CRT, CM, and CP, but decided she didn't even want to go to Donald's, as she preferred to sleep in that day.
When I went back in May I did breakfast at CP and enjoyed it as much as we did dinner in January. It depends on which characters your daughter wants to see, i.e. Mickey and Friends, Pooh and Friends, or the Princesses.
If I was only going to do one though, with a little girl I would try for CRT. Every little (or even big) Princess deserves to eat in the castle at least once. Read the thread at the top on this forum and use all the tips (punch 1 and 1 and immediately ask for CRT before the CM even gets through talking and hopefully you'll get it. I got it twice for last January and just cancelled the day I decided I didn't want, didn't even try for it in May, and got it again for this September.
