There is a huge difference between going out of your way for an obscure coaster and cannibalizing time at a good park for something crappy and stupid.
Personally, I stopped counting completely so that I wouldn't be tempted with a crappy and stupid roller coaster.
Something "obscure and unique" is one thing. Leaving a decent park, getting in your car, and driving an hour for some shitty Wacky Worm is another. IMO, if that's the thing kind thing you're into, that's great, knock yourself out, but we would have little in common.
As an example... When we went to India. We went out of our way to do the funky indoor looping roller coaster in a mall, but we skipped the crappy parks with shitty kiddie coasters that were only 30 minutes away in favor of spending more time at Adlabs Imagica and actually seeing Mumbai. Since I no longer count "credits" I didn't care about making an extra trip to ride dumb roller coasters and instead chose "quality over quantity."
That's all I'm trying to say.
Just my thoughts on the matter...
I personally, agree with robb i do count credits but i also like going to parks for some serious amounts of fun... For example Kings Island. i haven't been there in over 7 year's and went last season still a great place with good rides and some fun. i personally didn't count the credits just came to have fun.
