Recent months have brought showers to Cozumel which means the island as a whole is looking much greener again. Most people would be hard-pushed to know a hurricane had even passed last year.
Of course, when arriving by cruise ship the first things you see are the piers, which are still being repaired, but after that you will see very little damage anywhere and the island is in great shape.
I may be biased as I live in Cozumel and promote businesses here, but honestly, I've spoken with returning tourists and many say the island is better than ever now.

Hope that helps and we see you all again soon!
Best wishes from Cozumel
