We always try to choose an out-of-the-way spot to put the crib. Don't forget to bring a nightlight, so there is a little light so the baby won't scare if woken in a strange setting. With all of our kids, we all lay down and "go to sleep" at the same time. When the kids (especially the younger ones) are out, we get up and turn the t.v. on low. The kids never budge, especially at Disney because they are so exhausted!!
That has always worked for us. We've found that the kids have a hard time falling asleep if we have the t.v. on and we're moving around, but as I said, everyone is so exhausted after a day at Disney that this might not be a problem.
This is actually going to be our first trip, ever, getting two rooms. We are going to be so spoiled by having two different sleeping areas.
Oh, and be warned that baby's sleeping schedule may be "off" for a while....but it is SO worth it!
