Wow - it depends on how one defines appropriate.
I will say from a grand parent aged point of view - no. Though, one should also know that my roots are in fly-over country so I am, well conservative. I am sure that if a 5 yo was as the party it would not scar them for life, but frankly, it is late, there is a lot of drinking (more spectator) and folks are not looking out for kiddos.
I am sure there are many who will disagree but those are my thoughts.
