No there normally will be one language English / American. This can of course change if they have large contingency of a 'non English speaking' guest compliment, but this would be rare in the Caribbean. Yes expect the ship to be dominated by Americans.
Thanks for your help.
Hi , i have been with RCI many time now in the med and caribbean and ever time it is diffrent, some time lots of americans and some time lost of people from mexcio and america but they only seem to have the enterainment un english, the caribbean is the best and no matter what the mix im sure you will have a fab time .
We were on a RCI cruise last easter and the entertainment was done both in spanish and english. We didn't find that the ship was dominated by Americians again it had a good mixture of people.
On a cruise liner of medium to large passenger capacity, I would be very pleased if the majority of guests were American. I would count it a definite plus.
