I've heard that rumor several times, including a rumor of it being very "exclusive" with its own entrance in MK in Adventureland. I suppose it's possible, it just seems like the plot on opposite side of the lagoon for the Mediterranean would be the better location for views and big money for those views.
This rumor also fits with the widening of Floridian Way and addition of more overpasses for the parking exit. All these improvements (walkway to GF, widening of roads/overpasses) are all long delayed and MUCH needed to help with all the traffic congestion on property.
I just have to wonder with all the new hotels and additions to hotels at what point they reach saturation? And will the construction of more high end hotels combined with the low price point of the new Universal hotels force Disney to really cut the rates for the glorified motels/"value resorts"?
