Campgrounds with Seasonals. Yes/No?

Your broad-brush characterization of seasonals includes snow-birds, summer vacation rentals, and folks who live in their RV for any other reason. Maybe you simply don't like to be around anyone who occupies an RV site for a period longer than your 2-week vacation. It has been our experience that these days it is difficult to find privately-run CG's that don't have at least some seasonal/long-term residents; perhaps you should limit yourself to state and federal CG's where the maximum stay is 2 weeks.

Most of the summer I guess we might be people you would feel comfortable with since we like to move every week or two. But we tend to stay in place during the winter so might not be acceptable neighbors during those months. Does your opinion of people depend that much on whether they rent their site by the week or the season?

You have to check each park out carefully. In general I would tend to agree. But there are always exception to the rule.

I can think of two that we visit where I would challenge you to pick out the long term vs the daily/weekly. The reason being is the enforcement of rules that do not allow long terms to look or act any differently than short term.

we rarely stay in private owned rv parks or campgrounds. we prefer state and federal parks and campgrounds.
but when we do stay in an rv park, it's usually only for one or two nights so the occupants' status and behavior doesn't impact on us.

Maybe a little uptight, you really can't make a blanket statement like that IMO, I have experienced those types of places that you describe, but I have also stayed in nice places with seasonals who could not be nicer, give you the scoop on all the great things to see and do in the area, and always know where to find the best ice creammm!
