This is the first year I've had passes to any park; it really changes your perception of a visit. Before, I'd pay $20-$30 to get in to a park, and be pressed to get every last dimes worth of entertainment I could out of that day. Now, with Cedar Fair and Six Flags passes, things are much less pressured, because I know my fun doesn't end with the day. I'm spending more on parks than I did last year, but I'm having more fun and going more often. I'm also not spending money on other things, like watching the Tigers' horrible imitation of baseball. ;)
If I was paying as I went, you'd be sure I'd rather visit when TTD is up. That way, I'd be "getting my money's worth."
