I am sure someone on the board could recommend a good red plate driver who may do the trip for 250/300 US
I would be very sneeky and tell him/ your boyfriend or in Jamaica Your King, that you were going either to Ocho Rios, Dunn's falls, Dolphin Cove, Mystic Mountain or James Bond beach. You would be heading in that direction and then you would turn up at Runaway Bay.
I would even get the driver in on it and pretend he was taking you on a short visit to Brown's Town Market.
I think you might get away with it untill Brown's Town

(That's only me though. Sneeky.)

One love
B
