I rationalize it this way....keep in mind I would prefer it to be a lot less expensive but----
A nice RV spot on the ocean or within a block of the ocean in a resort with amenities like a big pool, jacuzzi, 50amp service, convenience store, public transportation, activities...etc is a lot better than my normal sticks & brick (S&B) setup. I'm not using electric, gas, and water at my S&B, I'm not going out to eat as much. I'm enjoying an nicer environment and staying warmer for a few months. It's worth the price.... which where we stay is about $65 a day.
