I'm terrible at writing an intriguing story that makes sense so I'll keep it as short as possible.

I started dancing with this girl in the group I was in (knew no one) and eventually she started kissing me, so I took her down stairs to another dance floor and we kissed again. After a bit of dancing/kissing i again took her to a smaller more quiet dance floor (I don't think anyone was in this room) and as we walked in I picked her up and sat down on one of the couches with her on my lap. She than starting kissing me more intensely than I had experienced before, so I saw that as a sign to start initiating a lot more kino and it seemed to be working awesomely.

20 minutes later we go back up to the group (that's gone now), so we talked for a while with lots of kissing in between. In the end she says "can I have your number?", I gave her my snapchat (different country). She said she was tired, we then left and went to her hostel entrance. I tried to initiate something but couldn't close and she left me with a kiss, I thought it could have gone better but she seemed keen when she asked for my number. Haven't heard from since.

Not hung up on the girl just confused why she was so keen on me and then poof.
