Since we have to drive 18 hours, I won't consider anything less than 10 days. Now, if I can be sedated and fly, (like I plan to in Dec. 2010), we'll stay 5 days. My DH is perfectly happy with 10 days, but I keep "extending" our trips. I'm bumping our May 2010 trip to 11 nights/12 days, and my DH keeps asking, "Are you sure you want to stay that long?". I always tell him that he's lucky we're ONLY staying 11 nights and that I'm working towards two full weeks.
