Med4bike, you really don't know what you are paying until you actually request a quote from them. I was surprised to see the low quote I got for the suite.
You guarantee with a first nights deposit but since I am only staying one night, I am paid in full already.

Editing to add, another good site to check for hotels is Alpharooms.com We got really great rates for our Rome hotel and they quote you in US dollars. The price they quote is the price you pay and you have the choice to pay when you book or 6 weeks before the reservation date.
