Carolyn has a great tour reputation at Mo Bay if you can get a group together to help share thus reduce the per person price. We didn't have a group, so booked with Belinda of a-zjamaicaplanners.com. We did exactly what you would like to do: Pick up at port with our names on a Clip board, Rose Hall Mansion tour (entry fee included) including a Rum Punch; tour of the countryside, stop and admission to Rose Hall Beach, again including entry fee and chair rental fee with a set time given by us for the driver to return for us; shopping at a local strip mall and a stop at Margaritaville (which we declined as we were tired). All this was $85 per couple. Our driver was Reyn and his lovely wife Ann joined us to celebrate her birthday. Our van was a fairly new air conditioned & very nice. We felt very safe and had a wonderful day. Whatever you choose, don't venture off on your own. You will be able to relax and see this beautiful country with a Barrett or A-Z Jamaica Planners tour. For Jamaican coffee, check out the prices at Rose Hall. I was surprised to learn it was cheaper there than in the shops.
Bon Voyage
