P.T. and Gloria have saved the Wonderland Motel, and now because of the celebrity tie-in with the Surf Monkey movie, the family of the Marquess of Hereferrshire is staying with them while they visit Disney World to loan the Twittleham Tiara to the theme park to display in the castle. The family, especially the young daughter, Lady Lilly, are all fairly snooty, but P.T. is so busy with the new motel restaurant and a sand castle competition that he doesn't give her much thought. The motel has sponsored a sand sculpting team consisting of Travis and Darryl to give the motel good advertising, and they do a great job. When the Twittleham Tiara is stolen, however, the reliable business of the motel starts to falter. The royals move out, and the Conch resort starts an ugly smear campaign saying that the Wonderland is not a safe place to stay. Blame falls on several employees, including a housekeeper and the cook in the new restaurant. With a reduced staff, everyone must kick in, which leads to less time to investigate the crime. P.T. and Gloria are on the case, and P.T. is also investigating whether Travis might be his father. In the end, they manage to figure out the theft, which has deeper roots than one might expect.
