Explorer of the Seas receives generally positive reviews for its service, food, and overall cruise experience, especially for families and first-time cruisers. Many guests praise the friendliness and professionalism of the staff, the cleanliness of the ship, and the variety of activities available. However, there are recurring criticisms regarding the ship's age and need for refurbishment, inconsistent food quality, crowded public areas, and issues with water quality in some cabins. Entertainment is often described as hit-or-miss, and some guests found the internet expensive and unreliable. Excursions and port experiences are mixed, with some guests disappointed by last-minute itinerary changes or lack of organization. Despite some negatives, many guests would cruise with Royal Caribbean again, citing good value and memorable experiences.
