Here's what my room looks like:
It's got a bathroom suite (separate bath, shower and lavatory, with two washbasins), a double bed, two HD TVs, a cupboard with a light that comes on when the door is open like a fridge, a 5-seater sofa, a table with 3 chairs round it, a desk, a printer/scanner/copier (no paper) and curtains that open and close automatically under electrical power when you give them a tug.
So, it looks like they ran out of single rooms and had to put me in a double suite. They were trying to get me to upgrade because they were going to put me in the upgraded room anyway. Just as well for me that I'm a cheapskate, then!
(Hmm, then again, maybe not: if I weren't a cheapskate, I'd have paid the $397 asking price for a helicopter trip to the Grand Canyon today, which, even though I really would like to see it, is a little beyond my budget).
