I used the 7 day php for my Dis con trip. THey can mail them to you or you can pick them up at their office (not far from Disney). I used 4 days while I was there and 1 plus. They never expire which is great. I did use the breakfast voucher for a Boma breakfast. The only thing I didnt like about the breakfast voucher is that its exp date was May 2003. I was going to buy these ahead of time for our next trip but the voucher was going to exp before then. If you plan on buying ahead I would ask the date on the voucher. They look like the ones that come from Connections/Simple Escapes.
The park ticket is a regular ticket not a voucher which I liked incase your in a hurry (as I was all during Dis con-lol).
