Patrick Mahomes' Super Bowl celebration went from hanging with some Chainsmokers to livin' it up with a mouse ... 'cause the champ and his crew were treated like royalty at Disnelyland on Monday -- and TMZ Sports has the video!!
The Kansas City Chiefs superstar and his wife, Brittany, brought Sterling and Bronze for the family-friendly fun ... and they were escorted through the theme park in a car as a ton of fans lined up to get a glimpse of the quarterback.
Of course, it's a quick turnaround -- the crew was raging into the early morning just hours ago .
