Anyone who's been to MK recently will have noticed a lot of construction going on around the bus depot. We were lucky enough to get a private bus back to POFQ tonight so asked the driver about it.
Apparently MK are getting new buses, to cope with the huge numbers of passengers they get, and to better assist those in wheelchairs and scooters. The buses will be the 'bendy' bus style. We actually saw one the other day, and they're quite a lot smaller than the ones we have in London but they're still pretty big.
If it works well at MK, these buses and new stations (which need to be bigger due to the size of the buses), will be rolled out (hehe, get it?), across the whole of WDW property :)
