I guess there are some families that genuinely enjoy traveling together. Dozens of people buy out plenty of space in a motel – or line up a few cottages – and arrive in force for some good ol' fashioned family bonding time.

Take out the element that looks forward to a large family trip every year, and you'll find a few more families at campsites, motels and vacation rentals ... though not entirely by choice. Difficult economic conditions are driving some to pool their resources, sacrificing a measure of enjoyment to make their travel dollars as productive as possible. From Hawaii to Maine, prospective travelers are looking for deals for large groups.
TripAdvisor puts the number of families with children vacationing with another family at a third, up substantially from 2008.
