MB garage is convenient because it's nearby to/from the arena and it seems secure. The 3 stars because the only access to and from are only the elevators or by walking through the entrance/exit where the cars also drive through. When the event ends, long lines to use the elevators and with covid, everyone is crammed together inside. In case of an emergency, having one exit is a safety issue: slow to get in and definitely slow to get out. First time using the garage, maybe i'm missing something?
For the price, there's gotta be a simpler way! But again, once parked you're right there. So, it's so-so.
