different ports excursions

We are looking at several cruises that stop in jamaica,but at different ports.

One is Ocho Rios,one Falmouth and one Montego Bay.

We also like the idea of a ships excursion that we have read about from more than one cruise line that does an island tour combining with the beach.

But I notice that those are only offered in Ocho Rios and falmouth.

I looked at a few private companies in montego bay and can't find something like it.

can anyone recommend?

I know this was long winded.

thanks

Looking for Montego Bay as well. Have you found anything?
