I'm closing in on doing the Disney "Grand Slam" (that's what I call it anyway!)
We've already done both California parks, both Paris parks and all four Florida parks. We've got a trip pencilled in for 2009 to Tokyo and we'll do both of those parks then, meaning we'll have visited 10 out of the 11.
Hong Kong I'm sure will follow on at some point after that - possibly as a stopover on the way to somewhere else like Australia.
