Fathom Depth – Cozumel & Great Stirrup Cay

About this cruise

If you don't need a long holiday but still want to get out on the water, this is a solid pick. 5 nights from Galveston on June 13, 2026, visiting Costa Maya and Cozumel. The shape of this trip works well: open water on either side with 2 port calls clustered in the middle. Snorkelling, palm trees, rum. Each stop does it a bit differently. Of the stops, Costa Maya tends to be the one people talk about: Mexico's quieter Caribbean escape among Mayan ruins. Around 9 hours per port on average, which is generous enough to go beyond the obvious. Mariner Of The Seas takes the food seriously, with 12 restaurants to choose from. 4 are included, and the rest are worth the splurge. Families and groups will find plenty to do: waterslides, shows, multiple pools, and something for every age. The timing works well too: warm evenings on deck, late sunsets, and a lively atmosphere. Sometimes the best trips are the ones you just go ahead and book.
