RV park
An RV park (alternatively known as recreational vehicle park or caravan park; hereinafter, the Park) is an area used for overnight or longer stay of those people who utilize recreational vehicles (also known by the acronym, RVs; hereinafter, RVs).
Tent accommodation
While few Parks do not allot separate spaces for RVs, most do. Those allotted spaces are often called "sites" and sometimes called "campsites". Nevertheless, true campsites and campgrounds provide facilities for tent camping by their definition.
Some Parks offer extended camping accommodations and even cabins, some have just camping spaces in addition to RV sites, and don't.
