I put down more than 3-weeks, counting how many nights for the year. Sometimes we've done more than 3 weeks at Disney, and sometimes less. It's not always just at
DVC. Sometimes we'll use an II getaway and stay in another off-site condo, and still go to Disney.
We're retired so time is not an issue.
Sometimes we'll take a shorter 7 to 10 day trip somewhere, but most trips are in the 3 to 8 week range. Our next planned trip to Florida will be just about 7 weeks long. (Only 14 of those days will be in DVC). After that it's not back to Florida again until December for about 6 weeks (Which will have about 15 days at Disney) In between the two Florida trips, we'll do some local trips in the RV, such as going to the Smoky Mountains.
