Salut, mon ami! I’m Colleen Lanin, founder of Travel Mamas & Grownup Getaways. I launched this travel blog in 2009 to make world adventures easier and more fun for explorers of all sorts. I love traveling via road trips, airplanes, and cruise ships. Nature? Love it. Theme parks? Yes, please. City escapes? Of course. Swimming in the best hotel pools? Nothing better!
