Passengers range in age from 35 - 55-plus with a large number of families onboard. Adventure of the Seas is a great option for couples and families -- particularly multi-generational groups. Speaking of groups, this a terrific cruise choice for them, whether it's a business group (there's a fully equipped conference center along with meeting space) or an extended family because there's lots to do for all age groups.

We offer the recommendation with one caveat: The sprawling ship and its plethora of options may be bewildering to folks who prefer more traditional styles of cruises.

Speaking of a mix of people, one of the more interesting facets of passenger demographics on this ship is international diversity (the daily Compass is printed in six languages). Adventure of the Seas, which is based in San Juan, also attracts a strong contingent from Puerto Rico and Caribbean islands beyond, which can make for a more varied blend.

Dress is quite casual as befits the Caribbean itinerary. There are two formal nights where most men wore suits and women wore dressy (but not long) cocktail gowns. Otherwise, people dressed in "smart casual" which varied from country club wear to dressy. We saw all types. A couple of nights were themed and you could wear, say, country-western garb or '50's styles.

Royal Caribbean passengers are charged $14.50 per person, per day ($17.50 for suite guests). Gratuities can be prepaid or will be added on a daily basis to passengers' SeaPass accounts during the cruise. Passengers can modify or remove gratuities by visiting the guest services desk while onboard. An 18 percent gratuity is automatically added to bar tabs.

Note: Australians and New Zealanders do not have the stateroom service charge added to their daily account; fares automatically include this gratuity as long as it was booked in AU/NZ dollars.
