Inexpensive Vacation Ideas

Summer is upon us and so is vacation season.  Here are some ideas for a thrifty vacation:

• Go camping!  Once you have the gear, this is a very inexpensive vacation.  Some campsites are $7-20 per night.  Activities are free, you bring your own food, the kids enjoy playing in the dirt, and great memories are made.
• Have a "stay-cation."  Lodging is free, you provide your own food, and you know the deals in the area.  Take time to explore your city.  Some activity ideas:  hiking, biking, swimming, museums, tour factories, visit geological points of interest.  Just be sure to act like it's a vacation, rather than getting caught up in the day-to-day life of cleaning, phone calls, tv shows, etc.
• Arrange a house swap with someone you know (or meet through reliable house swap websites).
• Visit family.  Just be a good guest and help provide and prepare meals.
• If you want to vacation somewhere more grand...consider going in the off-season.  Deals are much better and your dollar stretches farther.
