I agree with MBJ. TB is not attainable on a scooter. Once you get on the narrow roads the other side of Sav between Sav and Whitehouse, the road is OK but not great. With the sea on one side and the rock cliff on the other, I just can't see how you could do this safely. Also you'd be on the scooter 4 maybe 5 hours (not very comfortable) and a few hours at TB then a few hours at Floyd's there won't be enough hours in the day. Drive your self is an option but not for the faint of heart, unless you have driven Jamaica before and are comfortable do it. For a little more than the car rental why not just take a driver. Ask the driver to stop when you need to stretch, pull in if you need an icy cold Red Stripe. The driver can help you find a boat to take you out to Floyd's and recommend a place top stop for lunch. You can even have a sleep in the back seat on the way home after a busy day.
