In fact when I was a teenager, my family (parents, 3 sisters and 1 brother) travelled the US on a RV excursion! What a great experience filled with fun memories.....
Some of my favorite vacations were:
Moorea, Tahiti - celebrated our wedding anniversary and stayed in a water bungalow.
Maui - visited three times. My sister and brother-in-law lived there and were married there. They had a typical Hawaiian beach wedding including roasted Kahlua Pig and Ukulele music.
Paris - LOVED IT!!!! Every morning in our hotel we feasted on fresh croissants, jam and fruit. Nothing is better than French bakery items from Paris!
