Is the theater wheelchair accessible? And is there enough room to transfer the disabled to a lounge chair without having the wheelchair in someone else's way?

Yes

Yes it's accessible and there is plenty of room to make the transfer.

Indeed they are HC accessible & indeed there is plenty of room

Yes. When you take the ramp down into each theater, there is an extremely wide corridor that splits the upper rows of lounge seats from the lower seats. 3-5 people can stride comfortably side by side across it. The first of the upper rows is usually where the handicapped seating is. There are delineated spaced to park a wheelchair and lots of space around the chairs.
