Saved by the Bell

Kelly's grandfather Harry invites the gang for a vacation at the Hawaiian Hideaway, his hotel in Honolulu, but they soon discover that a rival is threatening to put him out of business, so they scheme to help save the Hideaway.

In this conclusion of the long running series it finally happens: Kelly and Zack will marry. Zack's parents are against the early commitment and Kelly's parents can't afford it, so only the gang travels to Las Vegas for the wedding. However, before the wedding can happen, they have to live through many adventures, including Zack losing his hard earned money, Kelly becoming jealous and Slater being chased by mobsters.
