Hey. My question is "How to handle this situation?".

Me, 21, an Exchange Student until August am currently being visited by my Family. My father died when I was 18 and after barely finishing Highschool, I left home to figure out my studies, career, life etc. But I have a younger sister (19 atm) and she is a huge fucking dick/prick/spoiled brat. She does not know any limits (guess why) and consistently creates an ultra shitty mood with me and my mother.

Currently, we are taking a rather expensive trip after long long time (and my mother got a loan for it and its very important to her, as she knows she wont likely be able to do such a thing in the future). But my sister is all-the-time saying things like "Don't talk to me", "Did i talk to you?" "Don't touch me". She makes stupid, annoying comments about any mistake we do or things we do not know (actually she won't even listen to explanations longer than 2 sentences, much less understanding/listening). Ignoring is not possible unless we leave her entirely behind. My sister is also dependant on money from my mother, so we cannot ignore her for 2 weeks

Example1: We went to Castle ruins today in a rent car (I was driving). And me and my mother wanted to see another place. But my sister told us "I don't talk to you" and went wandering, with her phone left in the car, not knowing the adress of the hostel and just wasting time. Cannot let my sister just there alone and drive off, can I? We wanted to go surfing later (it was her wish). (Took her anyway, which might have been a mistake). In the car, after wasting enough time already, she would just annoy me (driver) and my mom. Not wanting to close the window besides immense heat and just never shutting up and being offensive to us, her family members. I stopped at the side but she wouldn't leave (and I sadly couldnt call the police because we forgot our documents in the hostel - would it have been wise?) I really don't want to take away from her experience and from my mothers - she seems to want that we do stuff together, but it just does not work at all. Even the smallest things.

Example2: Just now my mom and me wanted to go into a restaurant but my sister didn't want to. My mother convinced her and after sitting at the table, she starts insulting us and when I want to get the Menu from her (waitress gave it to her) because she is literally just on the phone and blocking it - she grabs it and doesn't let us order. I swear, I wish beating people was legal.

My mother was so happy when we entered together to eat at this foreign country and finally united. But I couldn't fucking bear it, sitting at a table with this "human" whom I am blood-related and is insulting me and bullying her own mother. So I left and they did aswell (I knew it would be difficult for them to order because of the foreign language, but that was not the reason they left.)

I am writing this with urgency and so fucking sad.

TL:DR I am on a rare family trip (first after my father died) that my mother took debt (just in case, but we don't have much money nontheless) and my sister is constantly bullying my mom and annoying me. But my mom wishes to be on this trip together, allthough it seems to kill the trip for me and for my mom. Leaving my sister in the hostel for 1 day or so would likely make my mother feel sad/bad.

How do I react? Please help Give my mother an ultimatum? She should just leave her in the hostel, but she does not want to.
