Cozumel Entry Requirements

The first line of the source decides how the rest of it may be used.

The entry advice cited throughout this cluster opens by stating that the information is for people traveling on a full British citizen passport from the UK. Everything on that page is therefore the British position. This site writes for readers in the United States, so quoting it as though it described your obligations would be wrong in the way that matters most on an entry question.

What follows is attributed rather than restated. The visa question behind it is decided by the passport you hold and not by the port you arrive at, it genuinely differs by nationality, and the only authority on it is your own government. The country-level picture for any traveler is in the Mexico entry guide.

Passport validity is not a number of months here.

That same advice states that a passport must be valid for the duration of your stay. That is the requirement, and for a call measured in hours it is a low bar. Separately, and this is the half people miss, it records that the Mexican Embassy recommends passports be valid for at least 180 days, because 180 days is the longest a tourist may stay.

A requirement and a recommendation are different things: one is what the rule says, the other is a margin the issuing authority suggests you keep. Both belong in the answer. The trap is arriving with a fixed figure in your head from somewhere else in the region, because several nearby countries do set one and none of those numbers is the Mexican rule. Look at the blank pages while you are checking, since pages cannot be resolved at a pier.

The state entry tax, and the question the source does not answer.

The advice states that you must pay an entry tax to visit the state of Quintana Roo, and that you can pay the entry tax online before or during your stay. This island is in Quintana Roo, so this is not distant trivia.

Here is the limit, stated plainly. The same advice then describes the charge entirely in airport terms: help with paying online is described as available at Cancun Airport, and proof of payment is described as something shown at the airport before leaving. It says nothing about arriving by ship, and nothing else in this cluster research register does either. So the position is exactly this: the tax exists, the source describes an air arrival, and whether it is collected from your call, already included in something you have paid, or not applied at all is a question your cruise line can answer and this page cannot. Ask them before you sail. Asserting it either way here would be a conclusion of ours presented as the source.
