i'm a huge fan of comet! I've seen it twice - once in the lower stage right tables, and once in the rear mezz.
the lower stage right tables, i believe, were already talked about a bit on this thread. they're not exactly on stage, but they are above the orchestra. now, i know that some people had complaints, but i LOVED it! i got a lot of interaction! a dumpling was thrown to me by the amazing nick choksi, and i got an egg shaker! Denée came over to that area a lot. in the prologue, lucas came over to our section during the second chorus and i nearly fainted. plus, pierre walked by our section in the prologue, which might be the only time in the show where he leaves the area surrounding his salon. also, a highlight of this section is gelsey bell singing to you in letters! i made eye contact w a lot of ensemble members too. i would really recommend anywhere in that section.
i also saw it in the very front row of the right rear mezz. a lot of people hear "rear mezz" and think that the seats aren't very good, but i had an awesome time! i didn't get a dumpling, but the people next to me did. being right in front of a major walkway, i had a lot of interaction. i talked to one of the ensemble members named brad pre show, who recognized my friend and i at the stage door. (it was his bway debut! congrats brad!) as well as an ensemble member named celia. they were both very kind. we also got a cool view in the opera. when the actual opera is over and denée sings, the opera singers (played by gelsey bell and paul pinto) come up into the mezz and continue it! for the majority of that section gelsey bell was right in front of me. the illuminati section of the opera, when the ensemble comes out in hooded cloaks holding candles and fake daggers, was cool, because they walked right past us! it was funny because my friend and i were focusing on brittain and denée and then these creepy hooded figures were in front of us all of a sudden. dust and ashes was awesome because during the part where the cast joined in, a good chunk of the cast came to the walkway in a huge line to sing. we didn't get a letter, and i don't think anyone in the right rear mezz did. but letters are really random. the balaga/abduction sequence brittain ashford danced in front of us for the majority of it. gelsey bell came by a lot too. the people in my row ended up without egg shakers, but gelsey came by and offered her egg shaker to anyone without one.
the things that i have mentioned in this post aren't even half of the cool moments that i witnessed. i plan on seeing it again soon in the seat where lucas puts his arm around you during the abduction (i'm a pretty big fanatole if you couldn't tell lol)
if anyone wants to know anything about certain sections, please ask me! Iike most people in this thread, i'm very passionate about the seating chart lol.
