We used the 30 day Fun in the Sun pass the end of June beginning of July and had no problems.
We took our vouchers over to Epcot to get our real passes. The CM that took care of us had a small stack of them that she had already done. She got it out to double check something. She knew exactly what to do.
All we had to do was write everyone's name on their voucher and their birthdate. ( We had 7 vouchers so this took a while)
She had to enter everyone's info in the computer and then gave us our passes with everyone's name on theirs. 10 year old son was not thrilled to have Minnie on his
She also gave us back the portion of our voucher to be used for the breakfast and a sleeve for each pass.
THEN...about 5 days later I WASHED the passes. Got up in the morning and got the laundry out of the dryer and felt a lump in the pocket of my shorts. My heart dropped.
Took the lump of paper that used to be $1500 worth of passes (My parents still had theirs) and the photo copies of the vouchers that Paramount sent us to the Guest Relations window at AK and within 10 minutes we were issued new passes, no problem.
We also took our passes one day and went to Kennedy Space Center. Had no problems converting them to passed there either.
My mom, who hasn't been to DW with us since 97 just kept saying "how did you find these tickets, they are the best deal!!"
