I don't think so. They see each other so rarely now that we live across town. But they're both excited. Last night, Katie was all emotional about how her friends here are so flaky and Caitlin is one of her best friends and they never fight and they totally understand each other. I think it is going to be great for them to get to spend the week together. It comes at a good time.
I am sure they will do alot of things independently from us. I know they plan to sleep late in the mornings. I figure Chris and I will almost always be together, unless he is working out and I don't feel like it. Mom will usually be with us, but she might get tired and/or bored with us and return to the room for a break now and then. Katie and Caitlin will probably hang out with us sometimes when we go to the parks. We all enjoy the thrill rides and themed rides. Katie will show us some of her faves from her mini-trip back in May. She likes to "tour guide". And our rule will be: Always have dinner together.
We may not keep all of our ADRs, but at least we have them, and even if we don't do the planned ones, we will always meet up for dinner. That's the rule we used for our cruise last year. It was a way to make sure that we all got together at least once daily as a family and shared the day's adventures.
