Coming in late to the post, but I believe that RV'ing can be less expensive than staying at a hotel/motel. We bought an older 32' Class 'A' RV gas RV about 5 years ago to travel from Florida to Upstate NY with the grandkids. The overall trip for 21 days was about $2700.00. That included everything, campground fees, museum entry fees, fuel, and amusement part fees for 3 kids and 2 adults, which also included 2 dogs. The fuel cost was by far the most expensive part of the trip, about $1600.00. The cheapest we spent a night was of Blue Ridge Parkway at about $12. per night and the most was the KOA outside of DC about $67. The $67 as well worth the cost since for $10 the KOA had a shuttle that took you to/from DC daily. For the same trip, but without the convenience of stopping when you wanted and not having to eat out every meal, it would have cost us $4400.00. Why so much you ask? Well 15 meals a day, except maybe some continental breakfasts, car rental, pet deposits, and fuel these all add up fairly quickly. The OP didn't indicate how many family members went on the trip, but the average cost we usually see is about $30.00 per nights. We have stayed in many different types of campgrounds from rustic electric only to paver/concrete pads and the average is still the same. As mentioned by many of the previous responders location does account for some of the higher costs. If you travel to Key West, or on the beach, you are going to look at close to $100 a night. Stay about 20 miles from Key West and the cost could be as low as $50.00. These rates also reflect the time of year.
