traveling with another family that is on a different schedule. We're planning on going to WDW with my BIL & SIL and they're daughter. We have one son and at the time we go, my niece will be 5 and my son will be almost 5. They are consistenly always late. I don't want to spend my whole trip waiting around for them. For people that travel with others on different schedules, how do you handle it?
Yes he loves his family but not enough to spend a vacation with.
