IIRC, it was Bob Fosse who first bitched that ACL "talks a lot about dancing, but does very little of it." Personally, I don't think he was an unbiased source.
A poster above said there was dance only in the opening, closing and "Hello 12" numbers, but he was only counting the full-company dances. There is tap solo in "I Can Do That", a little ballet in "At the Ballet", etc. and so forth.
If you like to watch dance from the mezzanine, that's where you should sit.
Even when they aren't officially dancing, there's a lot of meaning in the staging, if it is anything like the original. Hint: there's a white line bisecting the stage. When the characters are on the line or in front of it, they are usually in the "present" (i.e., at the audition). When they are US of the line, they are in their past, reenacting their memories.
