Royal Caribbean International’s Mariner of the Seas will resume her Mexico port calls on June 21, according to the line. The Freedom, Liberty and Enchantment of the Seas all resumed their calls on May 24. Carnival Cruise Lines’ Holiday returned to Mexico service at the end of May, and the Ecstasy and Fantasy, on June 13. The remainder of Carnival’s Mexico-bound ships will return later this month.

However, both Norwegian Cruise Line and Holland America Line will not return to the region until the end of September.
