Just to point this out, from
@Orlandofan12 who mentioned of info he heard a few posts back,
Ride Portion of Sq Ft for MK should clock at 77K Square Feet, which is about in practice 1.76 Acres of space. If we were looking at
@Chris and his, he actually has it smaller than what KidZone's Building Size of MarioKart would've been (and more than likely Osaka's). In practice, the only way MarioKart is going to fit, unless drastically cutting, would have to be on Soundstages 22-25, not a mixture of Soundstage 22-25 & 28.
Essentially, Yoshi would nor the land as shown in Chris's image, would be fesible in that way, unless it takes 28 and a portion of Panda Express/Studio Deli/Restrooms.
And just to be a bit more clear..
Feet: 1,166.78 Feet
Square Feet: 77,000 Square Feet
Acres: 1.77 Acres
