OK... I will be on the opposite side. I have a tendency to consider spending the company's dime as though it is my money. I personally could not justify the cost of the high end hotels personally... and cant professionally either.
I oftentimes will stay at a hotel that is not the "preferred" hotel just to save $20 or $30 a night (often more).
I have yet to find a hotel where the service quality is worth $400 or $500 a night. I would be too guilty to use it.
Of course, I get funny looks in the office when I tell them I go to Napa Valley and stay at the "Chablis Inn" - you saw that place Tom911 (remember?).
Just another view.
