I do find it quite interesting, how in the same plot previously they could fit ~10 attractions (Mario Kart, Luigi Mansion Interactive Play Area, Bowsers Koopaling Airship Ride, Kong Jungle Playground, Monkey Mines Madness Coaster, Kirby Round flat Ride, Kirby Wet Play Area, Pokemon Training Academy, Koopa Troop Spinning Shells, Bullet Bills Flying Ride, Hyrule Castle Attraction, Interactive Navi Experience, kokiri forest village) all in that area. Now if looking at the certain lineup that has been mentioned we would be down to 7 attractions (2 interactive Mario Playgrounds, 1 interactive DK playground, 1 DK attraction, Mario Kart, Yoshi Island dark ride, and Pikmin play area.) Essentially moved down to no flat rides and 1 additional play area.
In the previous Mario Kart area, they managed to put three attractions into an ever smaller area (Mario Kart, Luigi's Mansion, Bowser's Airship).
So is Nintendo wanting more experiences and things to do within a small area or is the quality of the attractions in the reason of why Nintendo stated they wanted more?
