I'm away travelling and walked past a girl sitting in the open window of a cocktail bar. She gives me clear IOIs so eventually I go back in and sit on the table behind her. I decide to open her and her friend and they're both having a good time, both sending IOIs but because of my proximity to them it's impossible for me to escalate physically.

Eventually they say they're leaving but ask where I'm staying (clear indication of them wanting more from the night) but I simply tell them I'm staying in a hostel a ways away and they end up leaving.

How could I have handled that question?

The only idea I have is - 'At yours' with a 'hey I'm on holiday I thought I'd even cheeky' if it didn't pan out.

Other than that I have no idea. What could I have done so I know for the future? They're obviously looking for me to take the lead but I don't know where I could have steered it.

Context: I'm a pretty high SMV guy.

Thank you.
