Believe it or not, there's other things to consider with seasonal sites than awnings and slide outs in or out - like politics and drama.
I've been a seasonal for 12 years at a spot, and decided this is our last year. Seasonal site campgrounds are like a small city - except you're closer together, causing gossip to travel like wildfire. There are little 'clicks' that develop that speak ill of other little 'clicks'.
And, if you attempt to avoid the drama, and choose to just "do your own thang"... you're considered an outcast. Stared at as you drive by and wave - Think you'll get a wave back? Nope.
Almost sounds as if I'm speaking from experience, doesn't it? :) Maybe we are strange - but I don't go to the campground to get hammered Friday night, continue the stupor saturday, and Sunday wake up with a heck of a headache and drive home nauseous.
And if it's an election year? Forget it. Every arm-chair politician comes out in their white shorts and black socks and spews 'facts' they've 'heard' along the way.
I'm not stating that all seasonal campgrounds are like this... but the two in the area that I've got experience with -- are. I'm not sure how you would ever tell of issues in advance -- from the nightly camping side, it all looks so inviting. But it seems as though, for sure the last two years, it's become irritating to go to the camper, and it NEVER should be that way. I'm not sure if it's due to the polarization of America through politics (which is worse than I've ever seen it.) or what the deal is. But after doing it for 12 years, I guess it's time for me to hit the road again.
