21st Birthday Idea?

Ni
Hey so I'm turning 21 on November 15th and it's my last class for college (yay!) but I was never into drinking (yet I wouldn't mind having a few) but I just want some ideas as to what my SO and I can do. He said he's going to order me a wedding planner, my bridesmaids dress for his sisters wedding and a mini shopping spree at our local mall. I'm so excited! But I want to do something exciting maybe like a weekend in Atlantic City (I'm from south jersey). Idk! Ideas!?!!??
