I don't know how I missed that you started this, but I'm here and all caught up!
I agree that it is tough traveling with a group, and it can be a very different type of trip. We frequently travel with my family and DH's family, and while it is fun, I feel a lot of pressure to keep everyone happy and that can get a little stressful. We are going down next month with DH's parents, his sister, his sister's fiancee and his sisters fiancee's parents. I'm a little wary about this trip, because I don't know his sister's fiancees parents at all, and its difficult to travel with people you don't know. Its also challenging because they want me to plan the trip, and I'm reluctant to take the reins. Mostly because its Easter week, and I've been told that they want to avoid waiting in line, and don't want to be around crowds, but also don't want to wake up early. That's a catch-22 if I ever heard one, and I don't want to be in the line of fire when they figure out that its not going to work.
I hope things get easier as the trip wears on, and that your bounceback trip at least took some of the sting out of not being able to experience WDW the way you would have liked to.
