Plan for peewee sailors:
Royal Caribbean's fleet offer fun programs for little ones such as Aqua-Babies (ages 6 months to 18 months) and Aqua-Tots (18 months to 36 months).  Drop off programs start at age 2 for most family-friendly cruise line.

Thrill your teens, too:
With offerings like teen social hours, wave pools and Internet cafes, teens won't sulk.  FlowRide, a surfing simulator on Royal Caribbean's Freedom of the Seas and Liberty of the Seas,  is a hit.

Eat when you're hungry:
Prefer not to plan the day around a set dinner seating time many go for plans like Norwegian's Freestyle Dining; you'll eat when and where you want, and sit with whomever you like.  Princess offers a similar option, called Anytime Dining.

Cut more cost on your cruise:
Book early. best deals offered well in advance.  Book 6-12 months ahead to get the cabins you want at prices you'll like.  Go off-season.  Rates in the Caribbean are highest in winter and drop in summer and fall.

Cruising 101:
Bring some non-drowsy Dramamine or Bonine if you tend to experience seasickness.  Also try to book a cabin in the middle of the ship.  Cruises are often all-inclusive expect for alcohol.
