You need more than a week -- and perhaps an all-at-sea itinerary -- to experience all of Mariner of the Seas' public rooms! Thankfully, you can use the digital WayFinders to navigate your way around the ship.
The main focus, especially indoors, is the ship's fabulous Promenade. It's the pulse of the vessel. It's lined with shops (the usual cruise-style boutiques that sell logo items, duty-free liquor, perfume and cruisewear) and bars like the British-esque Wig & Gavel pub, the cave-like Vintages wine bar and the somewhat-elegant-but-mostly-bland Champagne Bar. However, the highlight is the 24-hour Cafe at the Promenade, which is a great place to snack and people watch.
Off the main promenade, in various directions, are the Lotus Lounge (the ship's secondary theater with entertainment ranging from line-dancing classes to cooking workshops) and the Connoisseur's Lounge (a very elegant, cozy cigar bar). Connected to the Promenade, via various stairways, are additional entertainment arenas, including Casino Royale, the Schooner Bar, Bolero's, the Savoy Theater and the Dragon's Lair disco. Tucked away a deck lower -- easy to miss -- is the ship's intimate cinema.
Studio B is located on Deck 3, with access only from the aft end of that deck, by the dining room; it houses the ship's ice-skating performances and activities, as well as occasional adults-only comedy shows. Arrive early for the best seats, as the theater is fairly small (though sightlines are good throughout).
Other public areas include a decently stocked library. The CyberZone is one of the more inviting onboard Internet centers we've seen, and it never seemed over-crowded.. The cost for Internet access, via bow-to-stern Wi-Fi or at a work station, is 65 cents a minute, or you can buy packages of 60, 100, 150, 250 or 500 minutes for $35, $55, $75, $100 or $150, respectively. The Photo Gallery on Deck 3 is the place to giggle over silly photos of your shipmates and buy your own for outlandish prices. BR>
For a great view, the Viking Crown Lounge area, sitting atop the main pool, is divided into three rooms. Ellington's, which transforms into a jazz club at night, is almost as popular during the day as a spot for quiet reading (and a bird's-eye view of the scene around the pool). Other areas include the 19th Hole sports bar and a dedicated quiet area.
We loved Vintages wine bar -- a new addition to Voyager-class ships, beginning with Navigator of the Seas -- with its cozy, wine-cave feel. You can purchase wine flights to do your own tastings of California wines. The fabulous and colorfully electric Bolero's (on Deck 4, under the Champagne Bar) was unfairly bypassed by many cruisers, and it seems as if its lively ambience would be more appropriate for the Promenade.
