I was a massive nerd in high school/elementary school, and all the girls knew it. But disappear for a few years to college, learn some skills, and it can be a remarkable change.
I ran into a girl from elementary school a couple of months ago at a bar. She'd become ridiculously attractive since then, and I walked over to her at a bar and struck up a conversation. She couldn't believe how much I'd changed, and told me a few times during the night that she felt sorry for not getting to know me better back then. She ended up coming back to my place that night...
Don't focus on "will they like me?". Go home, have some fun, and they should see you in a different light. Don't make trying to close them your primary goal of being home, as it comes off as being needy (with this girl, I stopped to talk for maybe a minute, worked the room for a while, got some phone numbers, then she came and bought me a drink and wanted to catch up on old times).
