I posted this message in another thread but I just found this one and thought it would be appropriate. I hope this helps someone.
Since someone mentioned give a day get a day I though I would let everyone know some info I received on the program. My agency was supposed to be one of the Volunteer agencies but things changed (at the federal level - way over my pay grade) but I had read all the fine print about the program because I was going to be in charge of all Disney correspondence. Anyway, just so you are aware, you do not have to use it for just one day's ticket! When you exchange your voucher for a ticket you can ask to apply it to Day 1 of a multi day ticket. The value currently is $71.10 - so if you are planning to buy a seven day ticket at $219.00, instead you can exchange your voucher and purchase your 7 day ticket for $147.90! Also you have to use your voucher by Dec 15th (but not the exchanged tickets, you can still buy the no expiration). They only have a set number and may run out before the year is out. If you have a season pass you can still use give a day get a day and exchange one voucher for dream fast passes for your entire group (up to 8 I think).
I hope I am not being redundant - sorry if everyone already new this, if not I hope you find it helpful!
