Geebs - that is how we put down the initial deposit on our wedding reception several years ago! We rolled up all our change, and had over $800! Good luck!
In addition to saving my change, I recently started writing checks out to myself, cashing them, ad putting them in the jar. Last week I saved over $30 at the grocery store using coupons, so I wrote a check to myself for the amount I saved! I also started seling all my used books on Amazon.com - when I receive my payments, that all goes to the vacation fund too!
There are so many different ways to save - each little bit sure adds up!
