A Base Ticket is one that will allow a particular guest access to one major theme park per day up to the maximum number of entitlements per ticket. A base ticket may have anywhere from one to ten days of admission. There are three options which may be purchased with a base ticket; each bear a relationship to the base ticket. Note that Base Ticket days cannot be used as entries to any of the minor parks.
No MYW ticket may have more than ten major park days of entitlements, unused or used, on it.
You are allowed to re-enter the same park if you leave it on one day, but it can only be used at the one park.
If you put the ticket in the turnstile of another park the display on the Guest side of the turnstile will be "ACCESS DENIED". The top line of the display on the Greeter side will give information about the ticket, and the second line of the display will say "CROSSOVER NOT PERMITTED". The turnstile will not unlock.
