@thomasart68,
I know you didn't want advice.
I'm going to offer a little, anyway.
Your trip pretty much guaranteed you would have feelings of loneliness. Traveling alone from city to city is a recipe for this, no matter how many people anyone has ever dated. Consciously or unconsciously, you set yourself up for those feelings.
So, what to do instead?
I think the idea of the trip was a decent one, to get out of your comfort zone.
Next time, look up local travel groups on Meetup and Google trips for singles and/or trips for people who share your interests. For example, if you like archeology, there may be trips for people to go to digs and actually, you know, dig up fossils.
Don't go in expecting or even hoping for romance. Go to make friends and have fun.
