Las Vegas

Piper's evaluation for the Concierge of the Year award tests her skills; Danny and Mike decide to play in a two-on-two basketball competition where the stakes become more than they anticipated.

Cooper, Danny and Mike are suspicious of a man who has a nearly perfect winning streak; Sam's whale brings his grandmother to the casino to play bingo; Danny gets convinced by Mike that he needs to do a "dry run" for the hospital.

Thieves try to steal a rare stamp that is up for auction at the Montecito, taking Danny, Piper, Mitch and the surveillance room hostage; Delinda loses most of her staff to illness and her restaurant has to close for the night, so Cooper offers to cook dinner for her; Sam plays hostess to a neurotic man and has no idea what he's really in Las Vegas.

Mike's mother finds out about his marriage to Piper and is upset, prompting Mike to put together a wedding ceremony, which in turn prompts Danny to formally propose to Delinda. Casey's little brother Vic shows up with plans to take ownership of the Montecito.

In the final season, only 19 episodes of the originally planned 22 episode season were filmed at the time the show was cancelled in 2008. The final episode ended with a cliffhanger with many issues left unresolved.
