Week-long, we usually do one every 12-18 months, due to my husband's schedule. We try to do a lot of smaller trips and sightseeing around here, though. This year, we're planning on going to Banff/Calgary and Glacier National Park, one in the spring, one in the fall. These will be 4-5 day weekend trips. DH also gets three "free" days when he gets home from a deployment, so we go to Seattle or somewhere over there. I think the next one, we're going to go to Leavenworth, WA.
