Quick Answer: Seven Seas Mariner is a Regent classic — 48,075 GT, 700 guests, launched in 2001. She was the world's first all-suite, all-balcony cruise ship, and remains fully inclusive with drinks, dining, and excursions in the fare. This page covers deck plans, live tracking, dining venues, and videos.

Best For: Loyal Regent cruisers who appreciate a well-loved ship with decades of refined service. Mariner suits travelers who value the all-inclusive luxury promise and don't need the newest interiors — she often offers better value than the Explorer Class ships.

Seven Seas Mariner pioneered the all-suite, all-balcony concept that now defines Regent. At 700 guests she is smaller than the Explorer Class (750 guests, 55,254 GT) but larger than Navigator (490 guests). Her 2001 launch means the hardware is older, though regular refurbishments keep her current. The all-inclusive fare is identical to the newer ships — specialty dining, premium drinks, shore excursions, Wi-Fi, and gratuities are all included. If you want the latest Regent experience, Grandeur (2023) or Splendor (2020) offer newer public spaces. If you want the most intimate Regent ship, Navigator is smaller still.
