What to know before you book
Cabin tips
Central Park balcony staterooms offer a surprisingly serene experience with garden views and are often cheaper than ocean-facing balconies. For a splurge, aft-facing suites on Deck 17 or 18 offer the best views and the least foot traffic.
Dining
Twenty-two restaurants include Hooked (New England seafood), El Loco Fresh (complimentary Mexican), and the specialty steakhouse Chops Grille tucked into Central Park. The three-level Main Dining Room handles the included dining with rotating menus nightly.
Entertainment
The Royal Theater hosts full Broadway-style productions like Hairspray, and the AquaTheater runs acrobatic diving shows after dark. Laser tag in Studio B gives the ship a unique edge for teens and competitive adults.
