Best way to purchase internet on Royal Caribbean Cruises is to get it for 1 person and 2 devices or 4 devices instead of each person having it for themselves. Also, always purchase internet before the cruise starts as it is less expensive and a better price. The Starlink internet is fast on Royal Caribbean Cruise ships. Older ships have just as fast as internet as newer ships like Icon of the Seas, Utopia of the Seas, and Star of the Seas, or any Oasis Class & Freedom Class ships.
