We just tightened our belts around here quite a bit. We have a baby on the way, my DDs 3rd birthday, we camp every year, and we need to do some updates on our house before we sell in the next 2 years, so we're penny pinching like crazy for the next year or so! Not to mention we are now planning a 2014 WDW trip, and we'd like to go all out this trip, so we're already setting money aside for that, as I'd like to make the deposit on the trip in August. I've decided I'm going to buy 1 Disney GC a every two weeks or so grocery shopping. If I have a LOT in the next year, we can use it towards paying off the trip, and the rest will be used towards souvenirs and drinks and whatnot on the trip.
I don't think I'd sell such a large thing unless I was SURE I didn't need it. We have 2 cars in our family, an unfortunate neccessity where we live as public transportation leaves much to be desired. My husband and I have crazy schedules due to theater and police work, so there's no way we could share a car without waking our DD in the middle of the night to pick someone up! We will, however, be having a rather large yard sale next Spring, after we are done with all our baby clothes, toys, etc. (we're only having 2 kids), and all of that would most likely go to our WDW trip.
