Search Results: ask her to prom

So my prom is on June first and I'm going with my coworker. I want to sleep with her but she wants to drink a little before and after. I'm ok with her drinking but should I get drunk with her?
I've never gotten drunk before so I'm scared about how I'll act. I don't want to do anything stupid or say something to hurt her.
I'm not a drinker and I rarely smoke weed, maybe once every six months, so I wouldn't know if prom is the appropriate time. I plan on getting us a hotel room, because our prom is at a hotel, so I don't know if we should get drunk there. I also have to talk to her as to whether or not she wants to get a room because I'm not sure if we should plan that out before or if I should ask her while we're at prom

The prom is on May 18, so I'm in a time crunch, but when is it too late to ask? (Girls, I'd greatly appreciate your input here.

I Im totally undecided on a date, so here are my options:

1. Ask this boring autistic girl to go with me. She's nice but there are reasons that I would never go out with her. Conversation with her is always very dry and detatched.
She actually tried to ask me out a while ago, we hung out, but I've ghosted her.

2. Ask a random girl. (I know very few girls due to me being a homeschooler).

3. Ask this girl I met online. She's graduated and taking a gap year, so she's unfamiliar with the school. Problem is, she's not very attractive to me. She is also kinda depressing (on snapchat at least. I have yet to meet her IRL). Nice thing is, she isn't ugly and we share political and religious views (I'm argumentative, so that's kind important)

4. Ask a college freshman I know reasonably well.

5. Try in a frenzy to meet girls and find one to ask.

6. Go alone.

7. Don't go.

So I'm bringing my coworker to prom this in a few months and I honestly have mixed feelings about her.
I'm bringing her because:
A) She asked me because she'd never gone to a prom because she left school early to help her family
and
B) I've got no one else to go with and I wasn't planning on going at all
So right now I'm trying to decide if I should get closer to her. Since we work together I figured I could get her something to eat next Saturday. I did spray us both with a milkshake last week, it was an accident and she was pissed because some coworkers laughed, so it wouldn't be odd to get her some breakfast.
Part of me wants to get to know her but the other part isn't sure about her. I feel partly happy around her, like last week when we tossed food at each other for fun, but at times she feels cold vibe wise. So should I get her some breakfast and see where it goes?
