MY CAT AND THANKSGIVING BREAK??

Ok, so my family owns a cabin about 5 hours away from my house. I have a cat, Carmen, and she is the most precious thing in the world to me! She is house-traind, not litter-trained, wich means she has a little cat door that she uses to go outsiade when she needs to the bathroom. She is mostly an indoor cat, but we leave her outside while we are at school or something. The problem is that we are going to my cabin for Thanksgiving, and we can't find anyone to take care of my fluff ball(CARMEN!LOL!!)! all our neighbors are going to be out of town for the holiday, my friends/family that live in our town are going to be gone, and all the pet hotel places are already full! what should i do? my parents want to take Carmen with us, but im worried about her having to go to the bathroom outside while we are at our cabin, and then either her getting lost, or trying to go back to our house(ive heard that cats do that!) should i bring her to our cabin with us? i think it would be a great experience for us both, but i dont want to loose her- she's so precious to me, and i cant bear the thought of her getting lost, or attacked by something while we r up there! so should i take her leash and go out with her when she needs to go potty, that way she is tied to me and she cant get away? what should i do? i ♥ my kitty so much, and i dont want anything to happen to her! what do i do? PLEASE HELP!
