What to do during the "limbo" time between the set-up of a date and the actual date?

So I met a girl online and asked her to grab a drink with me, she accepted and, unfortunately, I'm busy this weekend so I either have to try for sometime during the week or wait until next weekend.

Is getting a drink during the week (we both have class/work) a bad idea? I feel like if I try for next weekend, though, I won't know what to do for the whole week until then. I guess I'm just clueless, but would we just text for a week until the date? What's the best way to go about it? I don't want to learn her life story before we even get to the date, because that's what the freaking date is for.

Thanks!
