Going for 3 days - bring or leave?

On Saturday I'm leaving to go to my parents house for Christmas Eve, Christmas Day and Boxing Day, I'll be home in the evening on Boxing Day. 

Should I leave Leiki here with food and water, or should I bring her with me? She doesn't like the car at all and isn't too fond of new places, but she would be kept in my bedroom at my parents house while I'm there. The bedroom is on the second floor of their house, no one is really up there unless they're going to bed - so it will be quiet and her meowing won't bother people if she decides to do that the entire time. If I leave her at home, she'll probably eat all of her food during the first hour that I'm gone. 

What do you think?

Unfortunately, everyone that would be willing to do it is going home for Christmas as well, so she would be completely alone. 

The drive is only 30-45 minutes depending on traffic and white route I take, it's actually about the same amount of time that it takes to get to our vet, lol. 

She has become a lot more bonded to me in the past few months - she has always slept with me, but now she prefers to sleep ON my or right up near my chest, she will also come up to me for pets and hang out with me, which she never really did before. 

No one will really be at my parents house when I'm there, my sister and her kids (teenagers) are going to stop by for an hour or so on Christmas Eve, but they'll be downstairs with us and not upstairs. I will, obviously, still be sleeping in the room she'll be in and will go up and visit/play with her regularly. 

I don't know that she's unhappy when I'm not around, but it does take her a very long time to warm up to other people. It took her a few months to even let Mike or myself approach her without her running away, about 4 months for her to let us pet her and pick her up on a regular basis. It took her about 4 months to get used to people that came over regularly (friends), and she still prefers to hide if new people or people that she hasn't seen a lot come over. 

I don't think that she'll like the car ride much, but other than that I think she'll settle in fine as long as she's only in the one room (which she will be, my dad isn't even too fond of the idea of her coming at all, lol). 

We're leaving to go home in about 1/2 hour. I did bring her with me, it went pretty well. 

The drive there was annoying. I ended up blasting music so I didn't have to listen to "meow, meow, meow" and "whine, whine, whine" from the dogs or the cat the entire way, lol. When we got there I set her up in the bedroom with a litter box, food dish and some toys. She seemed pretty content the entire time. 

Unfortunately, holidays are pretty much the only time that I can't find someone to stop in and take care of her for me. All of my friends are either from out of town and live here now, or have family out of town and travel to see them. Everyone was going away while I was going to be gone as well - I guess that's what happens when everyone works retail and gets the same days off, lol. 

Overall it went well, I think the only part that stressed her was the car ride, but after that she was fine. Anytime we would go upstairs we'd see her paw sticking out from under the door, lol. My mom wanted so badly to let her out, but we knew that she would either knock the Christmas tree over, hide in the basement and we wouldn't be able to find her, or slip outside, so she stayed in the room.
