Me and a girl have made out on 3 separate occasions when drunk, does she like me?

[Skittle]

We get along well sober, and were both in the same group of friends, but we've only recently started talking, and we have banter back and forth on Facebook and via text. We even joke about stuff of a sexual nature aswell. Were going away with friends this weekend, and I figure this could be a good chance to find out if she does like me enough to go out with me. Just not sure how to go about it in a way where I don't end up looking like an idiot or a creep? She's a solid 10/10 which is why I'm sceptical of jumping in there and blowing the whole thing out into the open, a mate of both of ours hasn't spoke to her about it but says I should just ask her out? That's all well and good but how do I say it? I need some help here people

TIA
