The full name is "Bay Lake Tower at Disney's Contemporary Resort"
Regardless... you're focusing on the semantics of what is or isn't a resort and completely ignoring the point I made that, for most guests of the Contemporary (including those at BLT), the 10-minute walk to MK would be a perfectly viable option. If given the choice between a short walk, or standing around waiting for a bus, which do think most guests would choose? I really don't see how loss of the monorail would be as disruptive as you seem to think it would be. There has been monorail downtime before, and they've managed.
