Thanks for the responses - very helpful!! I'm hoping we get similar crowd levels as you both!
I have not been worried about the crowds until now - I called Disney a couple of nights ago to see about getting a room for my brother's family (last minute). All I kept hearing was "booked, booked, booked" and it freaked me out! Oh well. We have our touring plans in place and will just do the best we can.
Thanks for your input!
