I've read here that it is possible to use Disney World tickets at Disneyland - that you go to the turnstyle and they will change 1 day from DW ticket to a DL ticket. I will be at DL Monday and Tuesday after Easter. What is the best way to do the ticket exchange? Will they allow me to exchange a ticket on Sunday for use on Monday or does it need to be done Monday. I expect it will be very busy and am just trying to figure out the best way to use my DW tickets and not be holding up lines in the morning.
