More random pointers based on my experience... I was with a person using an
ECV so I had a different viewpoint for the two shows: Muppets and NBC sing-along.
My strongest opinion on seating is for the NBC Sing-along. Mobility device is either in the back or in the front. We were positioned in the front. For this show, you are seating below the footlights. You miss a teeny part of the stage and you are looking up at a severe angle. While you do get close up views of the "enhanced, very special set prop" (which is best viewed on the left side), it isn't enough to make up for the loss of perspective and view on the other aspects of the show. For a mobility device, I strongly suggest being in the back... unless you really, really want a close-up on the "very special set prop".
Best seat in the house for this show I think is middle-back to see the projection, stage and actors all in the same field of vision, next best middle-middle.
For the Muppet Show with ECV, we were positioned in the very front. Unlike NBC, we lost no aspect of the stage by being up-front. In fact, I was pleasantly surprised with the view, because I normally don't like to see a "broadway show" that close, especially with dancing. I normally like 1st row mezzanine, but way up front was a great spot. I came back to see the Muppet Show again, but on my own, and I choose to sit about 10ish rows back [from the front row] on the right. I had the most magical interaction with TIANA! Of course, that might be because I am muppet-type-of-person and was super-thrilled to see her (again). Who knows, maybe she recognized me? heh.
Anyways, I suggest middle-front for this show, but the show reads well from every angle. I would be happy further back, and if I want to see the whole ensemble formations in one field of vision, then middle-middle or middle-back for that comprehensive viewpoint/vantage.
I highly recommend the Muppet Show. It is well crafted, directed and designed in set/tech production. For those who are fans of Jazz as a dance style, you're going to see a few different styles of Jazz/Broadway, firmly in the classic era and it was a delight to see the flow in dance style. The music is a live band, and they are quite fun. 5 stars/highly recommend!
