I am a member of Outdoor Adventures (a Coast to Coast park) and I know several other TDR members who are. I bought my membership the conventional way, and probably paid too much for it, but I've gotten good use from it. Fortunatly my home park has expanded from two campgrounds to five campgrounds and four sister parks, of which I can camp for free (minus the annual maintenance fee). One of the new parks is within commuting distance of work, so I can stay there often without taking vacation days.
Most of the Coast to Coast parks are not close to any attractions. This is good or bad, depending upon your camping style. There are Good Neighbor parks, who honor the Coast to Coast membership, that are close to attractions, but it will cost more for you to stay at them, but they are still a lot cheaper than staying without a discount (about half). An example: We stayed at a Good Neighbor park, for ten days, near Orlando. Those ten days cost me a total of $110 for a full hook up site. The campground had a mobile home park on half of the property and the grounds were kept immaculate. That stay was a few years ago, so the price has gone up a little, but not much.
If you buy - -
1. There are alternatives to buying the normal way. Some of the guys here have purchased second-hand memberships for a lot less than the norm.
2. Get a locked in annual maintenance fee. Mine is locked so I pay the same each year as I did for the first year, which was in 96. They will let you lock in, if you ask, to make the sale.
3. Pay attention to the Home Park Packages. There are usually several packages that you can negotiate. One of my friends (not a TDR member) bought a ten year membership. My package will be passed on to my children when I kick off. Other packages allow inclussion of family members, like siblings, children and parents so they can camp when you're not there.
4. I believe the lions share of the cost to buy in is the Home Park's. You have to buy into a Home Park to get into the Coast ot Coast program though.
There is more... So stay tuned.
Why did I buy in? I wanted to buy some property in northern Michigan, so I could run up there for the weekends. After pricing property, thinking about insurance and taxes, figuring the cost of putting in electricity, a well and septic and then being locked to going to the one place all the time, the Coast to Coast program kept sounding better and better.
If you don't camp a lot, don't do it. I don't think it would be worth it.
