They had a one 9 day cruise to those ports and Puerto Vallarta in 2008 and we just loved it!!! Manzanillo was so beautiful and uninhabited and we had such a blast. I am going to book the 4 day on this ship to Cabo for this October. You will love it. I want to do this one again but Carnival had to go back to Aruba so I had to book that one!! Hope you will go you will have a blast!!
