We use CC USA and love it.
It has worked well - just a few glitches where a campground was listed, but dropped out. Minor annoyances. Otherwise, we take it into consideration when planning a day's journey - where we plan to end up. When we picked up our Scamp
in 09/2008 we left Backus on a 4 week trip to New England before returning home to California. During that time, we extensively used CC USA. And again, we used it this winter when we were gone 01/22 to 03/05.
We have seen different **quality** of parks - from "Boy would I love to spend time HERE" to "AHHHHHH - LET ME OUT NOW". But I think THAT just comes with the territory. Some are good, some are bad.
Overall we are very pleased and plan to renew every year.
Go to their websites and look at the participating parks and see if the areas YOU will be traveling to or through are represented. One of the other may serve YOU better.
