Have THE best 18th bday the south has ever seen...?

Ight so here's the deal. Where I live downtown is where you go to do ANYTHING bc everywhere else is just woods and all there is to do is go muddin and stuff. What's going to be happening is me and 4 good (girl) friends are goin to me and 4 good (girl) friends are goin to the beach, then headed out downtown for the night. When we go out that night my bf and best guy are meetin up too. About 3 of these people are underage so dk if they could get into a bar with us? I mean, there's a lot of scenery downyown mean, there's a lot of scenery downyown so there's lots of free places to just chill down there, but I wanna make this night unforgetable. Please please any suggestions. I would love to go clubbin suggestions. I would love to go clubbin but I donf think the underage ones could get in?
