Best for: Couples and adult groups will appreciate the ship's more manageable size, strong specialty dining, and tech-forward entertainment, while families still have plenty to do in the SeaPlex.

What to know before you book
Cabin tips
Virtual Balcony interior staterooms use floor-to-ceiling HD screens showing a real-time ocean view. They are a great value pick on this ship. If you book a balcony, aim for mid-ship on Decks 8 through 10 for the smoothest ride and quietest nights.
Dining
Seventeen restaurants include the standout Wonderland (imaginative molecular gastronomy), Giovanni's Kitchen and Wine Bar (consistently praised Italian), Teppanyaki, and Izumi for sushi. The three-level Main Dining Room seats 1,844.
Entertainment
Two70 is the star venue, hosting multimedia shows that blend live performers with massive robotic video screens. The North Star ride is a must-do on sea days, and the SeaPlex bumper cars are fun for all ages.
