Let's just say that you've planned your Disney trip and are spending a week at one of their resorts where the check-in time is 3:00 and you may not arrive there until 4, 4:30 or so and the parks are open until 6:00 (I say 6 because that's how late they were when we arrived for our trip in 2001 and we didn't get there until nearly 4:30 or 5 or so). Would you go ahead and buy a length of stay pass beginning with that very day you arrive although you may not get to do too much but really want to hit the parks right away, or would you perhaps hold off on the start of the ticket until the next morning when you have all day long to enjoy each park? The last time, we bought our length-of-stay passes beginning with that day, hit the Magic Kingdom right away, but were only able to do 2-3 quick attractions before the park closed. Does that seem worth it? If I get in that situation on my next trip, I know I'd really like to get to the parks right away, but on the other hand it may be better to wait til the next day and perhaps enjoy my first few hours in WDW riding around on the monorails or maybe visiting some of the other resorts or Downtown Disney.
