GT SCORE & GT STARS is our composite grading system for each ship based on spaciousness and service. The GT score ranges from 1 to 1,000 with a higher score implying a more comfortable, personalized onboard experience. GT stars are based on the score: below 200 points = *; 200 to 299 points = **; 300 to 449 points = ***; 450 to 649 points = ****; 650 points & above = *****.
