I’ve only gone once - about 2 years ago. DH booked as a surprise 3 nights. Afterward we wished 4 nights though, and plan to do 4 nights Sept 2027 when we bring our adult kids for the first time.
We are the type that repeatedly visit WDW and have seen almost everything over time. If you’re on the level of doing more than just attractions… time goes too quick. We spent time at Trader Sam’s and our pool while staying at DL Hotel, dinner at Napa Rose and checked out Grand Cali, arrived early to get good spot for the one night show during our trip,… all sorts of stuff like that PLUS trying to do most attractions. Had a blast!
We ended up missing a few of our priorities that one more day likely would’ve fixed.
