That is an excellent question - I hope someone answers this!
In my opinion, and from my experience with being at several concerts/performances there, the Fox theatre is not the type of venue that is conducive to being in the aisles (if you mean standing in the aisles during concerts)....as far as standing, at your seat, during a particular number, I don t think this is a problem.The Fox is not an arena venue but a smaller more subdued atmosphere. I have never been to any really crazy concerts there (so maybe it s different in those circumstances) but when I ve been there to see Sheryl Crow, Dido, etc., people have mostly stayed in their seats, or standing by their seats.As far as security, there is security there but I have never seen them be too aggressive; again, with the concerts I ve been at most people were respectful of the venue and the atmosphere.
It depends on what kind of performer it is..I went for a older artist and the security didn t care at all but then I went for the Jonas Brothers a few years ago and I kept getting in trouble for having a inch, literally a inch, of my foot in the isle.
I saw Godsmack there and everone stayed in front of their seats. Due to the atmosphere and how beautiful the Fox is, is it generally a tamer show.
