Hey RandomTokyoGuy, thanks for sharing! Now I'm more open to participating and I'll be sure to try the Ginza venue as per your suggestion. If anything, I can at least treat it as practice for my Japanese.
But who knows, since it'll be close to Christmas when I'm there, the girls may be extra desperate to get a date haha.
Any pointers on what to talk about since, as many have mentioned, you only get a few minutes with each girl?
