I saw the Trans-Siberian Orchestra perform at the Greensboro Coliseum in November of 2013. The parking was efficiently handed and both entering and exiting the venue was easy.
The small concert venue was NOT conducive to a good TSO performance -- I've seen the show twice in large arenas and loved the effectiveness of the lighting and pyrotechnics -- that didn't happen in the Coliseum.
Rest rooms were plentiful, but not overly clean. Concessions were limited and predictable.The stairs inside the coliseum are VERY steep and might be problematic for elderly or balance impaired individuals.
