Seven Seas Mariner
"Every cabin has a balcony, and the least expensive rooms are extraordinarily large—301 square feet—so these entry-level cabins are actually a great value. Unlike some rooms that are the same size but cost more, they're midship and down low, so motion isn't an issue. They even have walk-in closets." —Richard Turen (see above)

Seven Seas Navigator
"Balcony suite 601 is 180 square feet larger than the same-priced cabins one deck above. Cabin 600 has no balcony and a limited view, but it's 160 square feet larger than same-priced cabins on that deck." —Claudia Gordon, Betty Maclean Travel, Naples, Fla. (800-865-8111)

Seven Seas Voyager
"Book a suite along the stern, rather than the slightly larger ones toward the front. For several hundred dollars less, you lose only 14 square feet inside your cabin while more than doubling the size of your balcony. Since you'll be able to see what's happening off the sides of the ship as well as off the back, you'll have panoramic vistas." —Mary Jean Tully (see above)

ResidenSea
The World
"The Studio Residences on Deck 6, except 667 and 668, are the best value: They are the least expensive cabins that have unobstructed views and balconies. Cabins in category SR4 are about 30 square feet larger than those in SR3, with walk-in closets and vanities, yet on certain sailings they cost the same." —Brian Robertson, Robertson International Travel Consultants, Carpinteria, Calif. (800-969-3220)

Royal Caribbean
Adventure of the Seas, Explorer of the Seas, Navigator of the Seas, Voyager of the Seas
"I like the least expensive of the balcony cabins midship on Deck 6. On a weeklong Caribbean cruise, it's worth the extra $60 per person to get that balcony. But don't pay the additional $200 to upgrade from there, since you'll get only another 20 square feet." —Christy Buchheit (see above)

Majesty of the Seas, Monarch of the Seas, Sovereign of the Seas
"The outside cabins on Decks 2 and 3 are the best bargain. But make sure you get a room away from the bow—where windows have a tunnel view—and ahead of the aft rooms on Deck 3, which are under the noisy atrium." —Judy Lucas (see above)

Rhapsody of the Seas, Vision of the Seas
"The cabins facing the stern on Decks 7 and 8 have balconies that are almost twice as large as the others on the same decks but cost no more. Try to book corner cabins 7152, 7652, 8088, and 8588, since their wraparound balconies have fabulous views." —Sally Fish, Club Cruise, Roseville, Calif. (800-258-2732)

Seabourn Cruise Line
Seabourn Legend, Seabourn Pride, Seabourn Spirit
"Some cabins have minibalconies. They aren't wide enough for a chair, but you'll get floor-to-ceiling views, ocean breezes, and the sounds of the sea. Cabins 204 to 223 on Deck 5 are almost $1,000 less per suite for a seven-day Caribbean cruise than the identical rooms a deck above." —Leslie Fambrini (see above)
