When we were at WDW earlier this year we caught a WDW bus from the studios back to the GF. [This was a rare event as we normally drive to wherever we want to go!]
Anyhow we were sat on the bus for ages, just me, my DW and the driver who obviously was working to a timetable and had to wait at the bus stop for a given period of time.
I noticed that the seating arrangement on the bus was different from the one`s that I remembered from a few years ago and the driver overheard me mention this to my DW and joined in the conversation.
He then gave me three cards [about the size of a cigarette packet], each one depicting the different types of buses that WDW have used over the years. On the front of each card was a photo of the bus and some technical info was printed on the reverse of the card.
Apparently these cards are from a series of 18 [I think], relating to all modes of WDW transportation [boats, monorails etc.] and he said that all of the transportation CM`s should carry them and give them out when asked.
Maybe a project for the kids, to collect the full set?
