My sister and her boyfriend go to this ren faire every year for her birthday and I do think it sounds fun, but now I don't want to go. 

It started with my mom asking me a few months ago if I wanted to go because my parents had decided to go this year and I said that my sister hadn't invited me, so I wasn't sure if she wanted me to go. My mom assured me it was fine, so I said I'd go.

Well, I work at a hotel, so I can get 2 hotel rooms for less than $50/night and 2 for $75/night as my ceiling (there are blackout dates and such). **They can't get the cheapest rooms without me**. So, I got 3 hotel rooms and my dad insisted he was going to pay for them. He wants to do it. 

Cut to a few weeks ago, we found a cousin of my mothers we didn't know about a few ago and she moved here from out of state. When we were visiting with her the first night, she said she wanted to go and my mom immediately invited her saying there was space in my room. Luckily she pulled out, but the same day, my mom invited my aunt. 

I don't hate my aunt, shes fine, but I'm very introverted whereas shes super extroverted and she also hates it cold and I sleep in a fridge.... I cannot sleep if I'm too hot. 

I asked if they wanted me to get a 4th room and even considered just paying for mine and getting them another room, but I just don't have the money right now. They said not to get another room, even if I paid for my own room, because they had some unexpected expenses. 

The issue isn't so much sharing the room, but in my mom just volunteering the room to other people and to someone I'm not sure I'll feel comfortable sharing with. This also has me questioning if I was even truly invited or if my mom just decided everyone could go because we've never been on a family vacation. It's just going to be 4 days I want to end quickly. 

Also, my cousin is going to feed my cats, but I can tell she doesn't want to. 

Basically, I feel like I have to go now to keep the cost down for everyone else.

I know, I can choose to enjoy this weekend, but the prospect of pulling that much energy out of me already has me exhausted. I don't know what to do.

TLDR: Mother volunteered extra bed in my hotel room, I'm not even sure my sister wanted me to go on her bday trip, my cousin doesn't want to feed my cats (but agreed to), and I'm sharing a room with my aunt by no choice of my own and I feel like she'll make me very uncomfortable. Making a choice to have a good time seems like it'll take so much energy.
