It may not be true that two can live as cheaply as one, but two families can sometimes travel more cheaply than one. They can travel happily, too, if they decide beforehand how to split expenses and time together.
For example, if you're driving, will you split gas fifty-fifty or proportionally based on family size? How will you handle a blown fan belt or other unexpected expense? Differences in budgets may come into play, which can be make for uncomfortable discussions. You might agree on daily or weekly limits for shared, controllable expenses. For example, a frugal family can indulge their companions' taste for lobster one day, if the big spenders agree to dine on fast-food hamburgers the next. Or everyone can compromise on a family restaurant buffet.
Also, decide whether you're sharing only expenses or the entire vacation. Good times can be better, and cheaper, with friends. However, even best friends may have different ideas of what constitutes a good time. Will your family view your companions' plans for an afternoon at the wax museum as fun and funky? Or will it only mean less time for your outing at the waterpark? Differences in children's ages will also affect how much they enjoy shared activities.
Traveling with another family has the added advantage of reduced responsibilities. You may have someone to share driving duties and escort the gang to the restroom.
