Hop-on/Hop-off Bus Montego Bay??

I've seen a few threads mentioning something of a Hop on/off bus that drives through Montego Bay. Does anyone have any current info about this? Has anyone used the bus recently that could share the prices as well as the stops it makes? Is there a one time fee for the entire day or do I pay every time I get on? Is there only one hop on/off bus at the cruise terminal so I'll know what to look for when I'm there. If anyone has pics of the bus that would be great also. Thanks! ~1Cruisingal

I plan on doing this. From what I've researched on this forum, you pay a 1 time fee ($16, I think) & you ride all day. It stops at few of the tourist spots & then back. I believe its though Carnival. I'll be going in June, let me know what you find out.
