Well, I've found it to be quite worth it. I joined in 1996 and haven't regretted a minute of it. I joined while living in the north and though briefly about selling it when I landed here. I thought I wouldn't get much use out of it, but I was wrong! I use it more now than ever before!
I like the flexibility of the program, the perks, the overall cost. It's a great hedge against inflation and WHOOOOHOOOOOOOO I make my last payment on my DVC financed loan this month!
