I wanted GA floor tickets to Tenacious D but could only buy seated balcony tickets- will we still be able to get into the GA floor area?

Chances are you won't be able to... There's a bunch of ticket checkers who guide you to your seat when you arrive.

I don't know the rules for that show, but usually you wouldn't be allowed.

As a rule, tickets provide access only to the area indicated, and at sold-out or near-capacity shows, entrance to show areas will be closely monitored by ushers. At more sparsely-attended shows, ticket-checking is potentially more lax—but I wouldn't recommend centering your plans around that possibility.

If you are referring to Telegraph Club, yes you will certainly be able to gi anywhere patrons are allowed. There is an area by the sound booth that is elebated and has cocktail service during the ahow so you don't have to run to the side bars to get a drink. Fox Theater has done a great job providing an upgraded experience without leaving GA tickets feeling left out. There's also complimentary light bites provided and the Telegraph Room has its own dedicated enterance to the left of the GA box office. Ohand complimentary coat chec k

When you enter the theater they'll check your ticket. And if you have balcony they'll send you in that direction.
