I don't know about every body else but my best child hood vacation memories were not going to fancy places. As a child my parent did that, go to Mexico, Disneyland and a couple other places. None had an impact on me more then just plainly going camping. As boring as it sounds my best vacation memories as a child were formed on simple camping trip's.
Ever consider a canoe trip like the Bawron lakes. I did that with my kid's and today as adults they still talk about it, incredible family bonding time as there is no distraction, just nature at its best and extremely educational that has real impact on young minds.
that is true, I love them also but most kids now if don't have Internet and wifi they will lose there mind, lol
