Yes, in Hawaii there is a hotel so big there is a tram that connects all of the buildings. It is at the Hilton Waikaloa Village on the Big Island of Hawaii. If anyone has any information about this tram please pst it here.
I've seen glimpses of it on (of all places) the "Wheel of Fortune" TV show. They once taped a week's worth of shows at Hilton Waikoloa Village, interspersed with scenes of the facilities.
Here's a picture of it from Webshots.
Go to http://maps.google.com, search for "Hilton Waikoloa Village", zoom in, switch to satellite view, and you can see the trackway.
