Just wanted to share a couple more tips that we incorporate into our family travels.

Sleeping on the floor is a possibility
Sometimes you just miscalculate and think you have enough room for the family. We have found ourselves in this situation when camping and instead of everyone having an uncomfortable sleep on a twin air mattress, I have just slept on the floor. Same thing in a couple european hotels. To give everyone (myself included) a better sleep, just throw a blanket down and sleep on the floor.

Return from your trip a day early
We used to maximize every day of our vacation. We would come back late Sunday night and be at work first thing Monday morning. Now we always give ourselves a day at home before we begin our normal lives. It gets the kids settled into things and ensures you won’t spend an entire week playing catch up with laundry, school work or adult work
