Lionel Spalding arrives at the five-star Majestic Hotel on Wednesday, March 22, 1995 where he is accidentally drenched by an overflowing fountain due to a prank by Kyle and his older brother Brian, much to the stress and frustration of the hotel manager and the boys' widowed father Robert Grant. He is disappointed with the boys but they are guaranteed a vacation in Barbados afterwards, only to be forced to cancel the trip for a third time by the ruthless hotel owner, Elena Dubrow, due to the upcoming Crystal Ball where one of the guests is revealed to be a critic from the Le Monde Traveller Organization who they hope will reward the Majestic with a sixth star. At that moment, "Lord" Rutledge a jewel thief, arrives with an orangutan named Dunston, intending to steal the guests' jewelry. Dunston and his deceased brother Samson were both trained in thievery their entire lives. Now Dunston has been wanting to escape from Rutledge's poor treatment and life of crime ever since. Meanwhile, Rutledge distracts and causes Kyle to accidentally set a sterling rope mini-pulley free from his hand where Brian falls down and out from a laundry chute. Dunston flees from Rutledge and is later found by Kyle, who befriends the poor orangutan and promises to keep him safe. However Dunston soon begins causing disruption in the hotel such as ruining Mr. Spalding's workout and interfering with Mrs. Dellacroce's massage. After realizing Dunston's presence, Robert calls for an animal control specialist named Buck LaFarge to remove Dunston from the hotel. Rutledge searches the hotel for Dunston, and after locating him, ties Kyle up and gags him. Dunston and Kyle escape to the ballroom where the Crystal Ball is taking place, obtaining a picture of Rutledge, Dunston, and Samson from Rutledge's room. Kyle and Brian show the picture to their dad, and Robert is infuriated when Kyle says Rutledge tied him up. Brian and Kyle search for Dunston, avoiding LaFarge and Mrs. Dubrow, while Robert and Rutledge fight in the kitchen. Robert eventually stands up to Mrs. Dubrow, but is fired in the process. However, it turns out that Lionel Spalding, who had been humiliated, injured and inconvenienced by Dunston's antics, was the critic all along. As a result, Mr. Spalding declares Mrs. Dubrow managed to go from a five-star hotel to a one-star hotel. Rutledge is arrested and LaFarge apologizes to Dunston, who then punches him. In the end, thanks to the more kind-hearted Mr. Dubrow, Robert, Kyle and Brian relocate to Bali, to manage a Majestic hotel there and have even managed to keep Dunston as a pet. They invite Mr. Spalding over with a complementary room and meals to make up for all the trouble he experienced and assure him that nothing will go wrong this time. However, in the last scene, Dunston causes further trouble by dropping a large coconut which lands on Mr. Spalding's head.
