The 138,000-ton Explorer of the Seas is loaded with recreational amenities: an ice-skating rink, in-line skating track, rock-climbing wall, television studio and full-size, open-air basketball court. The Royal Promenade, which runs through the center of the ship, is longer than a football field and wide enough to accommodate three lanes of traffic. Here you'll find restaurants, shops, entertainment and street performers. The basketball court converts to a volleyball court, and there's also a golf simulator, nine-hole miniature golf course and jogging track. Adventure Beach, just for families, has its own pool. Spots for socializing include a champagne bar, cigar club, sports bar, jazz club, dance club and a cocktail lounge at the top of the ship. Hungry? There's a casual grill, ice-cream parlor, the Windjammer Cafe and Johnny Rocket's, modeled after an authentic 1950s diner (complete with jukebox). Portofino, an intimate reservations-only restaurant serving Italian fare, complements three main dining rooms.
