Choosing the right family vacation to keep both parents and kids happy can be a challenge. For those parents seeking an alternative to the traditional summer road trip or week by the seashore, a cruise might be just the solution. In fact, a cruise was the top vacation choice for the “perfect summer trip” in a National Geographic Kids survey that polled 401 children ages eight to 14.

For summer 2008, destinations include popular ports in the Caribbean and Mediterranean as well as lesser-known destinations in Scandinavia, Russia and Iceland. Cruises appeal to children because most major cruise line ships combine facilities and amenities for toddlers, young children and teenagers with a comprehensive program of supervised, age-appropriate activities, plus the excitement of traveling from port to port on the high seas.

Moreover, cruises uniquely provide both family “together-time” and “alone-time.” In addition to organized activities, kids can enjoy Internet access, water parks and video jukeboxes in dedicated private clubs. Meanwhile, parents can stretch out on adults-only sundecks and in relaxing hot tubs, or take in a couples' massage or enrichment class. On summer nights, babysitting services let grown-ups “paint the town,” including dining, dancing and moonlit walks on deck.

Following is a sampling of sailings offered by the major cruise lines that are perfect for summer family vacations:
