The longest WDW vacation was with a 5 day hopper pass, so it was 4 nights and 5 days. But like you guys, we always stay onsite. It does maximize the experience. I think over all the years we only left for a day trip to Sea World (when Alex was 10) and Universal twice. The bulk is spent at WDW's parks and resorts. We love to go to the other resorts and take in the exprience there as well. We have yet to hit the All Stars favoring the moderate and deluxe resorts. I would like to possibly stay at an All Star if that means more days for the vacation.
