Taking my 14D before she starts HS this fall, will be her 6th WDW/DL trip since age 3 and likely last as she has other trip interests (as does my 21S who got in 5 trips between ages of 4 and 14. Will be my 17th WDW/DL trip since early 70s and also last for a while, as kids and wife are more interested in other US and international trips in the future (have done some of those trips in recent years). Cost not really the issue, but other interests and having seen much of what DL/WDW recently and currently have to offer. Taking first cruise with wife later this year and looking at Europe and Hawaii in coming years, and other US sites. Personally will wait until 2021 50th WDW or later, and with major expansions all complete. After so many visits, and getting older with other interests, seems common to me that many WDW visitors like us looking for other trip experiences, not really linked to costs as all travel is getting more expensive for vacations involving as much as a WDW trip would (including activities, meals etc....)
