Advice please 🙏🏼

So I’m turning 16 in March and we’re planing to go Gatlinburg and rent out a cabin it was supposed to be just my Mom and my God Mother along with one friend and my boyfriend along with his one friend. Then my grandma also wanted to go along with my moms other friends witch in uncomfortable with that’s why I’m needing advice I would be totally fine if they came but they drink a lot and it’s super embarrassing and I would have to take care of them and my grandma is super rude when she’s drunk and I can’t just tell her not to drink or she gets upset with me. I just feel like my moms friends aren’t coming Bc it’s my birthday I think they just want to come to party. Am I selfish for not wanting so many grown ups to come? How am I supposed to tell them I don’t want them drinking?

And sorry I wasn’t sure where to post this 😅
