Barbday62--- we had purchased single day passes (we only planned 2 days at MK before heading to our family's house for the rest of the week) and used one day and got another non-expiring pass to return another time. we purchased single day becuz it was cheapest way for us to go at the time. we fly to florida every year to spend time with my in-laws and since ds is now 5 1/2, we decided to start detouring to disney to do one park a year for 2 days. so, the day we checked out, i was able to go to guest relations and get a late check-out (waiting for bil to come pick us up) and get credit for friday tickets. they actually offered a refund, but since i had the money to pay, i decided to take the credit. btw....if it was only dh and myself, we would have been at the park on friday...but, ds didn't even get up till 9:30am that day!! (spent the whole previous day in park since we only decided to have one day) .....so, i thank you for the info, but i did take care of it there!! can't wait to go next year!!!
