You need to discuss how each of you feel about visiting the other for this seminal event. Not being to either location leaves me with the choice of the more well known, Brooklyn.

Consider what the two of you wish to do and then what is available in each location. Compare & contrast then decide.

So me and my best friend (my sissy<3)

have known each other since we were 3 and it just so happens that we are 11 days apart,

so we were thinking about doing a joint sweet 16,

the problem?

She lives in New Jersey (Willingboro)

And I live in New York (Brooklyn)

Where should we have the party?
