The more social proof you can build the better you will do in any case.
A simple thign you should do is say Hi to EVERYBODY you see and do soem small talk and make their day somehow (positive vibes). This goes a long way believe me.
focus on meeting ALL the girls first in a friend terms basis. this will allow you to create comfort and select the your target more accurately.
After some time you have worked the venue and teh girls in there in terms of social, comfort and CASUAL friendship you can begin to focus on teh one you want.
By the time you select your target you should have created enough comfort with her for her to go at your place without issue.
Then, once you choose a atrget who is comfy with you, invite her over to your place to whatever non-sexual reason and escalate the vibe by creating lots of sexual tension (bedroom eyes, close proximity in a sofa side by side, touch, slow talking etc.).
Escalate till you fuck.
Do NOT pussy out and try to postpone the lay!
The ONLY way you will be able to make a girl a LTR is by having sex with her.
Get ANY sort of Maddona-Whore complex bullshit out of your mind.
Good luck and hope this helps you out.
