Be creative Rorogue, make an excuse and push to go to the chicks house, e.g. take her to her door and ask her to use the bathroom. If something like that is not possible then stay with her till sunset and take her to a low-key park, get some head then try bang in a bush/abandoned house. If she is not that adventurous you could ask a friend to let you smash her and say my house is being renovated so I am staying here. If you are lucky enough to have friends like that make sure to do them a big favour after or at the very least get them beers.
Ultimately, if none of that is available you can risk it and book an airbnb in a cheap place but this would be good on a 3rd date for example where she's less likely to flake.
