But more of the US can mean so many different things! I'd be thrilled to have sooo much to discover in my own country!
That is funny, we both see adventure going to the other’s home

I'm comfortable traveling the U.S. alone but I don't think I could handle an international trip by myself. My sister did a 6-week European cruise for her honeymoon and maybe I could do something like that with a structured itinerary and guaranteed transportation. They went to Italy and Greece, among many other places that I just can't remember.
I can't believe I forgot this but I went on a Caribbean cruise a few years ago and we went to Belize, Honduras, and Mexico. I got to hold a capuchin monkey on the beach in Honduras! I wasn't alone then but yeah, I think I could do a cruise by myself if I had to. I know the experience isn't the same and the port cities are owned by the cruise lines in most cases but it's still an adventure. We took a taxi all over Honduras just to see as much as we could. It was so beautiful!
My first solo trip was a cruise of the Mediterranean With 2 nights on land in Barcelona. The ship gave me confidence because I knew when and where to be, they all spoke English and I knew I wasn’t accidentally going to order octopus or something. Long story short, I was supposed to go with “friends” who never booked and then the travel agent didn’t contact me that my group hadn’t booked and put mine through so it was go or lose all that money. Temper got me to the airport, but the closer I got to it, the more scared I got. But I had a wonderful time! I was so glad I went. Saw Spain, Italy and France.
