Explorer of the Seas receives generally positive feedback for its friendly staff, enjoyable itineraries, and family-friendly atmosphere. Many guests praise the service, food, and cleanliness, but there are recurring complaints about the ship feeling dated, inconsistent entertainment quality, and issues with water quality in some cabins. Crowding, especially in dining areas and public spaces, is noted, as well as high prices for internet and specialty services. Excursions are a highlight for many, though some experienced logistical issues or disappointing ports. Overall, the cruise offers good value and memorable experiences, but there are areas for improvement, particularly in ship maintenance and entertainment.
