^That's not a date, that's a hookup. Correct me if I'm wrong, but I think "dating" implies that OP is eventually looking for a relationship, and hookups almost never lead to those.
Edit: that's not to say that nights in can't be a good idea. Popcorn, movies, games, etc can be a fun cheap alternative if you already know you get along well with the other person. And then you can let it lead to whatever, if things happen to happen.
