Just to amplify what Mark from our Member Service Team has posted, Coast Premier members are able to camp for free at all of our 200 affiliated resorts. If the resort showed you our current map, then yes, that would be all the red dots. Premier is our highest level of membership, and thus it is also the most expensive. Sounds like you are a current member, if you were to upgrade to Premier, you can still use your Trip Points to stay at Good Neighbor Parks. Trip Points you purchase no longer have an expiration date as of 1/1/2013, so you can use them now or in future years.
I hope this was helpful, let me or Mark know if you have further questions on this subject.
