Personally I think the TT Zone pass program is just about the best deal in membership camping out today. I will explain why.
MOST campground memberships are a lifetime contract, If you change your lifestyle or otherwise decide the membership is not for you they still want their dues.. I have one chain I used to belong to that is still dunning me for dues even though they closed all (or nearly all) the parks.. (The contract said they had to maintain the parks so they owe ME money, not the other way around).
TTs zone pass... Well if you subscribe to all the zones it will cost you (First year) roughly what I paid for my membership.. but after that you only pay dues, about the same as I pay. You can also subscribe to fewer zones.
One disadvantage is you only get 30 night free, then its a few dollars a night, 2 weeks in one out (Same as my full membership) but after 30 night in you have to pay per night, Not too bad though. plus you pay extra a night for 50 amp (But then so do I)..... I get up to what, 240 night free with my membership, Do not use quite that many as I only spend half my summer in TT parks (2/3 of the winter though) You also get a few parks I do not.
One of these days I need to re-visit Southern CA.
