This is all very interesting. I haven't paid any attention to this stuff since the last time we were at the parks, and we have always used the paper plans from the back of Unofficial Guide (and LOVED them).
At some point, my wife subscribed to the TP site, and I looked there first to see which days we should visit what parks next week (one of the busiest of the year).
Now I've just gone and looked at Josh's site, and I have to say his logic is very sound, but it's also very easy to predict what parks he will recommend (which is to say, his logic is easy enough to understand that once you do, he's in danger of putting himself out of business - so to speak).
So I've altered my plan based on what Josh has had to say, but will still use the TP touring plans. And bless Josh's heart, he's "opened up" MK from midnight to 3am on a day that he otherwise would have you avoid, which is exactly how I planned to use my hopper that day (with the caveat that I don't plan to do any parks the following day).
I'm glad so many people hate to plan, and hate to arrive at the parks early, because that means that while they're standing in line, I've already ridden the ride and am napping/sunning back at the pool.
Oh, and I'm bringing with me my hopper passes that I bought in 2006, and which I will use-up on this trip. It doesn't look like you can buy the non-expiring passes any more. That's really a shame.
