Season 3, Episode 21: “Let Us Entertain You”
An exhausted Carey hopes for a break in this episode, and no need to worry, the boys come to the rescue! Well, sort of. Unknown to her, the sneaky twins steal the lavish King Neptune Suite on the SS Tipton for a mini-adventure with their mother, granted the only condition for getting this suite for free is she sings.
After learning the real price to reside in the suite for the night, a shocked and tired Carey decides to sing, only to get sunburned right before. Now, the boys decide to take over the show and get themselves out of a web of lies!
This episode is a precursor to “The Suite Life on Deck” and was filmed on the same set as the spin-off series!
