I think the classfull madness of "/48 everywhere" should stop at some
point; the "every subnet is a /64" is enough already.

A /48 is 65536 *subnets*, with each subnet having space for what can be
considered "unlimited" number of devices.
A /56 already is 256 *subnets*. 
Now please show be a hotel room that has close to 65536 items in it
(also tell me how much does a night in such a room cost).
Then how many rooms may host close to 256 devices that can transmit and
receive data ?
And then again, at the end of the day a hotel is *NOT* and ISP, a hotel
is a hotel. Internet access is just an extra service that became
mandatory lately in order to remain "competitive".
