Ok here is the current situation. concerning Disney tickets.
You start out by picking your number of days, let's use 3 for example.
You pay about 80 bucks a day for an adult and about 70 per child ages 3-9. Under 3 is free, over 9 is adult.
For 3 days, you would pay about $240 adult, $210 child ages 3-9.
From there, you upgrade. To visit more than one park on the same day(waste of time and money), you pay a one time fee of $50 and the ticket becomes a hopper.
For about $40 extra, you get a couple water park visits anytime you chose. (bargain, considering the one time visit costs 40 bucks)
Depending on how many days you bought, there is a no expiration option ranging from 50-100 bucks. The tickets expire 14 days from your first use unless you do this.
If you figure out your cost per day on a 10 day ticet with the no expiration option, it comes out to about 30 bucks a day. Awesome if you will return at some point of your life, and Disney isn't taken under by the depression.
Whatever you chose, make a photocopy of the back of your tickets and put them in a safe place.
If you ever lose your tickets or run them throught the wash, the number on the back saves your ass and you get issued new tickets and don't have to buy new ones outside the Chucky Cheese.
