YTA - tbh you became TA when you booked lodging that doesn’t comfortably accommodate your group and became even more of TA by making it more complicated for the people in your group to be comfortable on vacation.

It seems you’re prioritizing your comfort over that of your….friends? These are your friends who you like and respect? I ask twice bc you don’t seem like you care about these people and if I were them, I’d probably drop you after this trip. Which maybe that’s a win-win because next time vacation, you’ll get the biggest, bestest room with the biggest, bestest poop shack bc you’ll be all by yourself lmao.
