The idea of full hookups and campgrounds is so out of my realm that I just don't see the attraction. Cut the cord and be truly free. Camp wherever you want whenever you want. You don't have to have any neighbors to worry about.
Special considerations are power supply workarounds. Lots of ways to do it, discussed here on a regular basis.
Waste disposal, will likely be the limiting factor. Still a week is easy for most anyone to do without dumping.
And finally.. Security/health&welfare. Depending on just how remote you go.. It may be up to you. Many places I go have no phone service and thus no 911. Any problems that come up, I have to deal with them myself.. I'm OK with that..YMMV
