Royal Caribbean doesn't stint on onboard entertainment, whether by day or by night. Daytimes (particularly sea days), the options are pretty run-of-the-mill -- bingo, dance classes and trivia contests.
Evenings, though, are a veritable six-ring circus. After dinner, you can start off at the two-deck Coral Theater -- shows specializing in Broadway-style ensemble singing and dancing were big hits there. Then maybe catch a movie, join in the Battle of the Sexes competition, or hit one of the bars for a variety of musical performances. Check the daily schedule for karaoke, which takes place at night in the Safari Lounge.
The real action, though, can be found in the ship's numerous bars. On top of the ship is the Vortex Disco, a funky bar that revolves. It's primarily the ship's spot for late night revelry, but it's also a great spot for a pre-dinner cocktail at sunset. Also up top is the Hollywood Odyssey, a cozy spot that is a favorite for cigar-smokers.
In the evenings before and after dinner, the bars surrounding the atrium are vibrant and lively, particularly the Champagne Bar and the Lobby Bar. Off the main path a bit is Royal Caribbean's trademark Schooner Bar -- it's in the space between Chops Grille and Portofino. You can tuck into comfy booths or hang at the bar. Just past the Schooner Bar is the Safari Club, which hosts private events and serves as a secondary showroom.
To get a different perspective, head to the Crown and Anchor lounge on Deck 12, where you can peer straight down (through reinforced glass, of course) to Deck 4.
There's also a very smoky casino with the usual slots and gaming tables. Located right off the casino, the Pit Stop is ostensibly the ship's sports bar. It's hard to hear any of the coverage on the handful of televisions because of the ringing of the slot machines, and it's quite smoky, even on the nonsmoking side.
The ship also has a small cinema on Deck 6, which is nonsmoking but fills with smoke from the nearby Pit Stop.
On port days, Jewel of the Seas offers a variety of excursions. In Key West, excursions lean toward tours, while the Caribbean ports -- including Cozumel, St. Kitts and St. Maarten -- tend to be water-based and, therefore, more active.
