Kibby, you can route taxi it 3 routes for well under 10....closer to $8. It would be no more of an experience than riding the subway in Philly....prolly much cleaner and safer.

Some say the affordable route route taxi system is not for tourist as it deprives locals from transport.....find a single person in any taxi park that feels this way....or any taxi operator that wants to turn down your business...

The private way is good as well....just confirm your price and amount of stops. Some people want to make 1-100 stops along the way and turn a 90 minute ride into an all day tour of the island thingy....gotta think about this when you price it out. Be fair and kind to those private drivers....
