The Lynx bus runs from the Transportation and Ticket Center to SeaWorld, where you can get a free transfer to the Lynx that runs down I-Drive, or else catch the I-Ride trolley at SeaWorld. The Lynx buses are the 50 and 8, but I can't remember which is which! Nearly sure the 50 is from Disney, then the 8 at SeaWorld. We did the Titanic exhibition last year and it's great, really interesting and really well acted by our tour guide!
