ET has the details...

How did newlyweds Mariah Carey and Nick Cannon cap off two romantic weeks together in the Bahamas? They went to Disney World, of course!

The famous lovebirds spent Tuesday enjoying the Florida theme parks' wild rides, including the Rock 'n' Roller Coaster Starring Aerosmith, the famous indoor coaster Space Mountain (Nick's favorite ride), and the stomach-plunging Twilight Zone Tower of Terror (Mariah's favorite.)

They also met up with the another power couple -- the biggest in all of Disney World -- Mickey and Miney Mouse! The dynamic duos mugged for photos at Disney's Grand Floridian Resort and Spa, and Mariah really got into the spirit of things by wearing "Tinker Bell" earrings and a designer t-shirt depicting Mickey and Miney sharing a smooch.

She and Nick planned to top off their fun by taking in the "Wishes" fireworks show set to the backdrop of the Magic Kingdom's iconic Cinderella Caste.
