The whole "-Ticket" thing really bothers me. Why not count the duration of rides? It's now pretty easy to find out how long attractions are in minutes and seconds. One could tally up the number of minutes of "experiences" at each park. This would be more meaningful than the ticket designations or the number of attractions.
If you're counting "ride time" - how do you count an attraction like "Casey Jr. Splash 'N' Soak Station" - there's no "time" on that - if Magic Kingdom is open 9am-10pm, then the "ride time" on CJSNSS is "13 hours", as you could spend the whole day there.
