I Completely agree with that. They have this massive sprawling parking lot that requires trams to then get to a boat or monorail to then get to the resort. Insane!
(2) wide 3 floor garages would be fairly low profile, and provide all the parking of the existing lots. Creative design on the Poly side with a bit'o'landscaping and they could do 4 levels to gain spaces and still not make any significant impact from MK. They can even alter the monorail express beams on that side to provide a station at each garage, eliminating the need for trams.
[Edit] Tap your MagicBand and you can board the monorail. Other wise you can buy tickets at a kiosk or CM staffed windows for the park(s). Curious how many people could then stream line their entry for boarding direct to MK. Could justify an additional train during busy times as their would be additional stations and direct capacity management.
