Plan around the youngest traveler
Naps, snack times and bedtimes do not take a vacation. Schedule the big activity in the morning and keep the afternoon loose.
Let the kids help plan
Give each kid one pick for the trip. They will be more excited and more patient through everyone else's choices.
Choose lodging carefully
A suite or rental with a separate bedroom means the adults are not sitting in the dark at 8 p.m. A pool is often the highlight of the whole trip for younger kids.
