In the past we have done 5 to 7 night trips and we definitely felt TIRED when we got home, so for this past trip(our 4th as a family) we stayed in WDW for 9 nights 10 days and plus a day on either end for traveling. It was SOOOOO nice.(the 5 night was a whirlwind). I am writing a slow TR about it now. It was wonderful. We had a no park arrival day, then 3 days of parks, then a rest day that wound up semi-rest!, then 2 days in the parks, then a rest day, then our last day in the parks. On departure day we chilled out, left late. SO worth it. I am not sure I want to go back for less days in the future, but my bank acct may choose differently. Esp if we want to get back thee sooner!
Go!!!
