Hi!
I wouldn't give up too quickly. The waitlist may work. I have a reservation for a two bedroom for the first week of December which I will probably cancel. I reserved it just in case one of our trips works out then. Actually, the first trip planned has moved to January (best time for my bro-in-law). The second trip is completely up in the air and will probably happen before December. Anyway, I will cancel as soon as the other trip is set.
Good luck,
Regina
