My main issue with that bus is that it stops at a LOT more hotels. There is no maximum number of hotels, on top of that it sometimes makes you transfer buses at DLH to another bus, adding more time to the equation. To me its not worth the extra 3 dollars between any shuttle service and the bus for the extra time, easily up to a half hour sitting on a bus. Ive never felt unsafe in the shuttles, usually its traffic all the way from Lax to Disney and the shuttles take the hov lane so you're travelling in traffic at the same speed as traffic around you.
