With everything from surfing and rock climbing to skating and basketball - not to mention intriguing ports of call - it's no surprise that cruising is one of the fastest growing sectors of the travel industry. Many believe one of the best vacations for families is on the high seas.

Over the past decade, multi-generational cruising in particular has taken off. "Cruising is definitely popular with families, mostly because everybody can do their own thing, get together for dinner and then do their own thing again," says Expedia CruiseShipCenters spokesperson John Felice. "Your time together can be both ship time and time ashore."

Here are some hints to help your family get the most out of your floating adventure:

Take advantage of kids programs. Many cruise lines offer children's programs in distinct age groups and with their own facilities, activities and counsellors. If it matters to you how much time your kids spend playing video games, set limits. Enjoy adult time but don't forget to take advantage of opportunities for shared experiences as a family.

Keep in touch. One of the appeals of cruising is that kids can enjoy some independence, but if you don't want to worry about connecting with one another on a large ship, find out if your cruise line offers a pager service. If not, take along your own two-way radios rather than cell phones and save costly international roaming charges.

Some ships have security bands for kids and pagers for adults. "The kids know that they don't have to find their parents in an emergency," says Felice. "They just have to find a crew member who can help them."

Set a budget. The all-inclusive nature of cruising means you're not constantly shelling out for food, drinks and snacks, but consider purchasing a soft drink package if your kids consume a lot of pop.

Shore excursions can also add up. It's often possible to explore a new town on your own rather than on paid tours. Research your ports of call before departure and prioritize your favourite excursions or activities. Infant care and babysitters can also cost extra. Also budget for gratuities; ask about the common practice for your ship.

Book a balcony. If your children nap during the day or go to sleep long before you want to call it a night, consider a room with a balcony. It's a great place to relax in the afternoon or to enjoy a drink together in the evening.

Pack appropriately. Boys can get away with a polo shirt and pants in the dining room, but most ships have a formal night that requires dressier attire. You may be tempted to forgo formal night to free up space in your suitcases, but it's truly a memorable evening the entire family will enjoy. Take advantage of on-ship photographers and leave with a family portrait you'll treasure.

Pack a swimsuit and change of clothes in your carry-on bag, as it can sometimes take hours for your luggage to be delivered to your stateroom (and you know the kids will want to hit the pool right away). Remedies for seasickness will be available for purchase on board but you may want to buy some common prescriptions - such as scopolamine patches, worn behind the ear like a tiny band-aid, and herbal remedies like ginger - in advance.

Exercise caution but have fun. "As with any vacation, families should exercise caution and be aware of their surroundings when visiting ports of call," says Vance Gulliksen of Carnival Cruise Lines. "Be sure to try as many new experiences as possible, whether it's trying a new food or snorkelling for the first time."
