As has been said previously, one of the greatest cost savings in using the RV is also a great convenience. That is the cost of meals. Just this past week, I was in a nice hotel in downtown Dallas and breakfast for myself and my 1 yr old granddaughter was right at $20. This was a cup of coffee (plain, nothing fancy), a cup of milk, a single egg and cheese croissant, and a cup of fruit. Had we been somewhere in the RV, i could have made a pot of coffee for what the one cup cost. I also could have fixed scrambled eggs, added some cheese, had an entire cantaloupe and some strawberries for everyday we were there for the same cost as the one morning.
although I prefer to drive and take my RV, sometimes I fly or just drive because of the time constraints.
