Thanks for the back-up, Nails.
When I used to visit Vegas as a tourist I only saw the room when my eyes were closed if I ever even saw it' at all. So I never was too damn concerned about upgrades.
I used to save sleep for the flight back to sanity.
But one hotel receptionist whom I knew from a previous visit gave me a room (she said it was the Elvis Suite) that was so damn huge that it took a couple of minutes to walk from the bed to the bathroom.
