Many cruise lines have minimum-age requirements, so ask before booking if you're traveling with an infant. But most new and large ships do accommodate wheelchairs; arrange through Accessible Journeys, which specializes in wheelchair travel (800/846-4537).

The great outdoors can be a good destination for families traveling with animals. International campground chain KOA (koa.com) allows pets at all of its locations, although each one has its own specific policy—for example, some don't let dogs stay inside cabins—and all require leashes.

Active trips help keep fidgety teens' moods from souring as the days stretch on. Look into sea kayaking, wildlife exploration, and volcano hiking with Thomson Family Adventures (familyadventures.com). There are trips for kids as young as 6, and those 11 and under get deep discounts.
