Getting passport stamped in Cozumel

I'll be cruising to Cozumel and costa maya in November and really want a Mexican passport stamp does anyone know how and where I can get it stamped at in Cozumel? All the posts I've read on here are quite a few years old I was wondering if anyone had recent information

There are places on the piers at customs immigration kiosks/offices that provide this. You can also check with your ship's guest services. Some ships will gather passports and have them stamped for you and returned when customs and immigration come on board.

Post office in Cozumel will do it. It was a $12 taxi ride roundtrip.
