Can I play multi player Challenge Road in Mario Party?

Solution 1:

A bit late response, and not one you might want, but - no, you can't play challange road using multiple controllers with multiple people.

Challenge road is intended to be a single player experience. The only way you can make it "multiplayer" is hot-seat game, where you and other people just pass the single joy-con around, but that's as much as multiplayer it gets.

Why Nintendo made it as such, I don't know. Especially because some of the minigames you play along the challenge road are Team Minigames, where the bot character you get to play with on the same team can literally ruin your otherwise good round of minigame.
