I use Knutsfordexpress every time I can. Many times to Kingston and also mobay. It's the safest way to travel on the island or at least it feels that way. I was just in the Negril office this morning checking the schedule and fares to Port Antonio, $3400 ja one way very cheap in my eyes. Yes a taxi might be faster but I much prefer safer over faster. The bathroom is very clean in the buses that have them. Watched a movie on the way to Kingston once the bus had drop down screens. I highly recommend them.
