This situation concerns me a great deal. Since 7am yesterday morning the new news stories off the AP etc, have increased the number of reported cases every hour.
As I leave on Saturday for the 7 night western. I am in no way looking forward to stopping in Cozumel. I just don't think it's worth the potential risk. Illness tends to spread on a cruise ship very fast. I don't even want to run the risk of staying on board and getting ill from the folks that get back on at days end.
I would encourage everyone traveling soon with itineraries that have stops in Mexico to phone / e-mail
DCL and voice your concern. There are plenty of other ports / places to go to instead.
