I#d been in Ubon in February this year. I hat a contact to a lady via TF. She was divorced with two kids lived in a house with her mother. She was a school director (as I was), I went to her school several times. It was funny.
She took me by her hand when I arrived at the airport, I thought I've been in Paty 🙂
Then she said to me in the car she wouldn't sleep with me before we are married 🙂 (that was another red flag in a different way 555)
We went out with friends in different places , f.e.Tawan Daeng. Very loud but beautiful young ladies there.
If you are in special sites you will know where to go to meet P4P girls in massage places and others. I found the city very relaxed. But it better you speak Lao becauce people there speak Lao not thai.
