I have been traveling alone for over 30 years. It was the best thing I ever did for myself-you discover things about yourself you might not have if you always travel with family or friends exclusively.
I began doing so even when my family was young and I was married-Since my husband died over 11 years ago, it was a very easy transition regarding travel,and all other social events most often done with ‘husband, boyfriend, friends, other’ because I already did this for myself.
I never really cared what people thought about it-I will add that regardless of all the benefits, one always has to keep in mind watching your own back-I learned this on my very first trip away, and never forgot it. Happy Travels!
