No, it's not. People who happen to own a second home somewhere they can go will often go for a few months but the dad has to stay and go to work.
Most families that get a vacation plan on both parents being off work for a week or two at some point during the summer and they plan a short trip.
Our last vacation was to Branson MO in September. We went to visit friends and spend 2 days at Silver Dollar City. It was a lot of fun and cost about $1000. If my friend had not been able to get discount tickets to a show or two it would have cost less because we could not have afforded the ones we saw. But it was very much worth it seeing them.
The vacation before that we went to Billings MT to visit friends and saw sights all along the way there and back. It was really nice too.
My friend that lives in Branson had a vacation home in the islands off in the Caribbean somewhere. She would take the kids and go for a few weeks then come back to her psychology clinic then go back again for a few more weeks before summer was over.
This is a huge exception though. Most people in America are really struggling to make ends meet due to our poor economy. Having a vacation home is not very likely and if they did have one they probably have sold it or are trying.
In times of old I think Americans lived a lot like the wealthy people did in Dirty Dancing. They would pick a place for vacation where they could return each summer and over the years they would get to know others so it would feel like visiting family. The family in Dirty Dancing did stay there for some time. The dad took off work from his medical practice and the whole family stayed together. But a lot of the women who were there during the week had husbands who came only on the weekends. I think that is how the wealthy probably lived at one point.
We don't live like that anymore. It's not cost effective and too many people just care about money more and saving it up.
