Trip points are a 'payment system' used by Coast To Coast (C2C) for private campground site use.
As a C2C member you make a reservation at a private campground......campground charges you 1000--1500 trip points per night for basic site.
As a C2C member you purchase trip points to be used for private campground nightly fees.
$10 equals 1000 trip points
If you purchase larger quantities you can get some bonus trip points.
The private CGs allow affiliate memberships to use their CGs.
Affiliates are C2C, AOR, RPI, ROD etc. that can be joined AFTER having a membership in a 'home park' (private CG).
We purchased a 'home park' with C2C affiliation for $950 total.
Then paid yrly dues to maintain home park and C2C memberships.
Used home park and C2C during our 7 yrs of FT travel. Made nightly site fees very reasonable. Just ONE of the ways to control/lower living expenses.
