Hmm. The issues I see doing this (live in Nashville) would be the Arena and the Stadium. Those places are posted - no carry.
Metro PD is give and take - some officers are of the 'you should conceal or not carry' and some do understand.
Sadly, due the situation where there will be tons of people from all over the nation, there will be someone who reports you, or even confronts you. Be expecting this. Be polite and know the law.
Also, remember, look for the "Gun Buster" sign. If it is there, no go. The issue you will find is this: Your group will want to go into a Country and Western Bar, and it may be posted. You do not go in, or you better have a place to secure it close by. Be careful. The signs are easily missed.
