Selection of Campgrounds??

We have been FT since Dec 2012, Also like to travel, problem, Finding CG's that meet our requirements, Clean, Neat, Polite Host and Workers, with decent sites, large enough not to hear your neighbor snore., or what other things they might do., also while traveling, the Cost of Daily Stays, especially in area that one might want to visit. Hard to get park service, coe, or other sites on a short notice., we do not like to make long term reservations. I know if you can stay by tht week or Month that will save money, but some of the parks are not that good that one wants to stay for a lengthy stay., I know it may be us, spoiled, cement pads etc. Where do you go when you want to sit a spell? We do visit Myrtle Beach for extended stays., kinda Home Base;we also like to use our Golf Cart..Also go to Fl during the Season. But would like other place or places to roam a little., mostly east of the Mississippi River.
