Hi Lucy,
I am booked on the Splendor on 05/10/09. More likely than not, Carnival will be cancelling all Mexico ports, the same as they did for the 05/03 sail date, a result of the swine flu.
They will confirm things this week. If they make this change, I will cancel and book the Halloween cruise. I think I'll have more fun on this date.
I'll post again when I hear further from Carnival
PJ
