ok so our kids are finally at the age where we feel we can start traveling without too many annoyances and we want to head out west. flight price for all 5 of us will be around $1800-$1900. Driving the family car would be too brutal so the only two other options would be to rent a car or an RV. If we rent an RV we will need a car to get around in once we're there. I'd like to do the cross country RV thing but worry it might be way more expensive than flying. I can't decide what to do so I need your input to help me come to a decision.
