Back in the day, all the time. If you were an AP holder on a day visit, fine. For a vacation, no way! I guess being spontaneous can be fun and exciting, but it's definitely not the smart way to maximize your time or money.And I mean completely - no planning at all, just deciding what park when you get up. No FP, no ADR etc... Just total spontaneity. How old were your kids and how did it go? Especially if it was busy time?
