Yes. In a cool night you may need it
If the blanket were in a bag yea but not to use in the venue itself there are seats only
I'm sure they would allow it, but there really wouldn't be a need for it
It's a seated Auditorium so there is no need for a blanket. But if you would like to take a blanket to put over your lap they will permit it.
What do you mean?
