According to my TA that time is valid and we will be one of the 1st in. However, last year we were a noon ressie and we were the 1st ones in then - my girls were picked to be princesses of the day and we went in to take pictures with Cinderella by ourselves and then upstairs to an empty dining room (if a remember correctly) but I could have been caught up in the surroundings!! This is what was making me nervous about the time. Since my friend made the ressies I feel a little apprehensive about asking her to call back and verify - its just a little awkard. But I don't guess it will hurt it is their first time going. I will let you know if we find anything else out.
