We have a trip planned to WDW in Oct and a trip to DL planned in June of 08. Our plan is to buy the amount of tix we need (10) before our Oct. WDW trip as no expiration hoppers. We know that we can exchange our tix in Cali. for DL hoppers but it has to be done EACH individual day because the ticket has to be used on the day of the exchange. Here is the question....How hard is it to exchange the tickets each day? Can it be done at the concierge desk at the DLH (where we are staying) or does it have to be done at the park each day.....that would be bad. Thank you so much in advance.
