Summer — with its intrinsic air of freedom and relaxation — is especially well-suited for taking the trip your family has been dreaming of since the height of winter. This is one of the only times of year conducive to family travel, and there's a lot of pressure to spend your time wisely. But it can be tough to choose a destination that will please everyone, and it's even more difficult when you have to consider factors like weather, affordability and overall atmosphere.First, recognize the settings in which your family thrives. Is your family full of beach bums who love the serenity of a Caribbean vacation? Are you itching for some hiking and adventure in a national park? Do bustling cities keep everyone entertained?
