Cozumel is still tendering and from the looks of things last week when I was there.... it will be tendering through at least the end of the year. Work on the international pier is progressing ... but it is slow going. Likewise, the main pier near the main shopping on San Miguel is also a work in progress.
I was there in February and we had to tender. It does not even look like repairs have begun on the pier itself yet, so you will have to use a tender. However, the process was simple. Not a hassle at all!!
