Louis has a scheme to raise money for a snowboarding trip for himself, Twitty, Tawny, and Tom. While everyone else is out of the house on a weekend night, he plans to turn his home into "Stevens Manor," a bed and breakfast inn, and he's already got guests' reservations! When his parents leave on an anniversary trip, he and his friends put on monogrammed shirts, redecorate the house, and greet their new arrivals, who find that the staff includes Tawny playing cocktail-lounge piano and Beans as a masseur! Despite some near-disasters (like Tom turning out to be an obnoxious waiter), the guys seem to be pulling off their plan.
Meanwhile Ren is at a sleepover at Ruby's, who is down after breaking up with her boyfriend. The two plan a "boy-free" evening, but when her ex calls on the phone, Ruby spends the night talking to him. Ren goes home in disgust and climbs in her bed only to find--there's someone already in it! Ren hits the roof when she finds out what Louis has done and is immediately on the phone to her parents when she gets a load of the cute twin boys who are staying at the house. All of a sudden Ren joins the staff at Stevens Manor rather than reporting Louis to her folks. Ruby comes by to apologize to Ren and she too takes one look at the twins and joins in the ruse.
Then some real trouble strikes. Eileen calls home to check on Louis and through a mix-up (there's a guest there also named Louis), she thinks her son has injured his back. She and Steve cut short their trip and will return in two hours. Louis is sure he will be busted big time, but Ren comes up with a desperation plan. It's midnight and everyone is in bed, so the kids sneak into every room and reset all the clocks and watches to 7AM! They proceed to wake up all the guests and feed the groggy, bewildered people a not very appetizing breakfast, then practically push them out the front door, telling them check-out time at Stevens Manor is 7AM! Louis and company feverishly rush to put everything in their house back to normal again and they just barely get the job done before their parents arrive. Eileen and Steve don't suspect anything until they see a woman on TV give a "thumbs up" review to Stevens Manor and its hip, young staff!
