We usually do 1 trip per year and try to go for at least 10 days. Coming from Canada, it’s often too far/expensive to do multiple trips in one year, although buying into DVC 4 years ago has made that easier. We are actually doing a big trip this December for 10 days and then coming back in January for a cruise (non-Disney) and tacking on a few days at Disney afterwards. But generally we do longer trips, to avoid as much of the Canadian winter as possible!
One trip per year, the length has crept up from 10 nights to 12, occasionally 13 nights, except this year, this year it’s 2 ‘short’ trips, one for 8 nights, the second for 9 nights .
We have decided that 8 days is the perfect amount for our family, lets us have 2 days at each park. We usually only go to AK for one day, but it is nice to have the option, plus we usually hop from on park to another one in the evenings to go to a sit down restaurant.
