5. Oceania Cruises

On Oceania ships, there are no supplements for most specialty restaurants (including Jacques Pépin's bistro, but not La Reserve); non-alcoholic beverages; or onboard fitness classes. Plus, complimentary shuttle buses are provided in some ports.

Ca-ching!: The "OLife Choice" package option bundles in loads of extras for guests who pay a premium fare. These include airfare from some U.S. cities, unlimited internet access, and a choice of a beverage package, shore excursion bundle, or shipboard credit.
