What to know before you book
Cabin tips
The Deluxe Veranda Suite (301 sq ft) is the entry category and already has a balcony. Concierge Suites are the same size, the Penthouse Suite (449 sq ft) adds room, Horizon View Suites (627 sq ft) step up again, and the Signature Suite (2,002 sq ft) is the top cabin.
Dining
Every restaurant is included in the fare, with no surcharges. Compass Rose is the main dining room, Chartreuse serves modern French, Prime 7 is the steakhouse, and Sette Mari at La Veranda serves Italian. The Pool Grill and Coffee Connection cover casual meals.
Entertainment
Evenings bring cabaret shows, karaoke and the casino, or a quiet spot on deck if you would rather skip them. Unlimited shore excursions are included in the fare, so days tend to be spent ashore.

Caden Sorenson runs Travel Vient, an independent travel research site built on a verified database of airline baggage rules, airport connection times, cruise line policies, and eSIM plans. He built the verification pipeline behind it: each record is read from the company or government page that publishes it (connection times: OAG data via ExpertFlyer), stored with that source link and the sentence it came from, and re-checked on a schedule. He is a senior staff engineer with 15+ years building software, a Computer Science graduate of Utah State University, and based in Logan, Utah.
