The bus system is complicated to plan out to be exact heres why....well this is just what I have observed over ther years and that they did on our last trip.
-Some times the buses start at south, go all away around and stop at south again before heading to their destination.
-Some start at south then W,N,E and on to destination.
-In the am when there are alot of ppl heading for one park and the bus fills to capacity it dosent even go around the loop just on to destination. Usually when this happens there are other buses that start at west and on around.
-In the am and after I think 4 or 4:30 por and porfq have seperate buses to MK. In between during the slow time they share.
-Ive seen them start at POR then go to PORFQ.
-Been on them where they start at north then east, then PORFQ then back to south, then west then back out the back way and on to the destination.
-Buses to TL and BB share with other destinations, in the AM BB,TL are the first stop. In the PM TL/BB are the last stop(to keep wet ppl on bus for shortest time).
-If a bad storm comes they divert alot of buses to TL/BB because they want to get as many ppl away from there that want to leave because of lightning.
-If you want to take a bus from your room to south (food court) or vise versa ask the driver because he might not be going all away round where they might have the day before.
-If a bus pulls up and the sign still reads POR ask the driver because he or she might have forgot to change it for some reason.
-If you get on a bus to a park, forget something and plan on just staying on the bus and going back to your room, again ask the driver because now days their routes constantly change.
-If you have a PS, Show or parade to get to at a certain time allow at least 30 min ride time. If you have to transfer allow 1 hour. Just when you think it will take you 15 min to get from your room to your destination you will (and I say will) get a driver that seems to take a new way that seems to be sight seeing tour of the property all at a speed 5 MPH under the speed limit. I once asked a driver why we went past MGM to get from POR to MK, he said he was way ahead of schedgule and needed to kill time.
Oh if it could only go back to the days of the colored flag system on the buses.
