Here come the crabs!

I'm going to a wedding memorial day weekend in Baltimore (aka Crabtown) and b/c I like to plan ahead, I bought my ticket way in advance, before my friends who said "Yeah, we're going to stay through Monday" but then all decided to leave Sunday instead b/c it was cheaper and now I'm stuck there for a day by myself. I mean, it's not the "by myself" thing that really bothers me, it's the "I have no money" thing that's the problem. So now I'm supposed to pay for a hotel room and entertainment, aka lame a** touristy things? And I'm running out of alternate options, as I will list below:
1. Visit friend Jenny in DC on Sunday night. That was the plan until she decided to go away w/ her boyfriend that weekend. She's getting laid...I'm getting screwed. I'm so clever it hurts.
2. Go to New York for the night. I don't think I want to take a 3 hour train ride there and then back just to save money on a hotel. That would be stupid, no? (I'm French)
3. Change my ticket to Sunday. Sure, there's only a $25 dollar charge to exchange it, but w/ the additional price change I'll owe over $500. Which doesn't really work out so well with the "I have no money" situation. I f*cking hate plane tickets.
4. Fly back stand by on Sunday. What if I wait for hours and don't get on a flight? Essentially, I would be using the airport as a hotel. I would be like a homeless person. I wouldn't be able to shower. I couldn't put on my pajamas. If I happen to have an empty cup sitting beside me while I'm sleeping, someone may even put money in it b/c they feel sorry for me and think I look like a good kid who's on the wrong path. Then I would use the money to buy myself a treat- like ice cream.
5. Per my mom's suggestion, meet someone at the wedding who will let me stay with them. I don't know if she was implying that I whore myself out to the best man for a free night's stay at his apt, but I think I might take her advice. I know hookers who've done a lot worse for less (I don't really know any hookers).
