ROA takes up as much space as all of TSL, including the TSMM buildings. That's 7 Haunted Mansions.What’s the point of filling in ROA?
Right now there is one ride and one walk-thru attraction in that space. So, capacity would be *greatly* increased.
Also, it solves the problem of getting to the expansion area North of HM/RoA and NW of BTM.
