AITAH for refusing to keep the hotel room at 80°F on a school trip?

Me and my friend are at FBLA for a school event, sharing our own hotel room. She wants to keep the room at 80°F, but I told her the highest I’m comfortable with is 75 because 80 feels way too hot for me.

She got really upset and started saying that 75 is “too cold” for her. I suggested she could use blankets or ask the hotel for extras, since I can’t really do anything if I’m too hot. She also won’t let me use a fan because she says it would make the room too cold, and she says blankets don’t help unless they’re heated.

This isn’t the only issue. Earlier, she got really upset on the bus because she didn’t get a window seat, even though I offered to let her lean on my shoulder since I get carsick and needed the window. She also took about 2 hours to get ready to go swimming after I had been asking all day, and by the time she was ready, the pool was closed.

The whole trip she’s been in a bad mood and now she’s making it seem like I’m being inconsiderate for not agreeing to 80°F. I feel like I’ve tried to compromise, but she only wants things her way.

AITAH?
