We just signed up to help clean up a neighborhood in Fort Walton Beach next Saturday. In exchange for our 4 hours of work, Disney will give us a free one-day-one-park ticket! I'm not sure how we'll use this yet, since we're planning to get annual passes this year. We are planning to buy tickets for some other people later on this year; maybe we'll be able to use our exchange vouchers for them. Who knows? I have read that there are alternatives to the free ticket, such as special fastpasses. We're excited!
PS - Our Disney Vacation begins 21 weeks from today!
