The other problem with some of the online hotel booking sites is that some chains, like the Kimpton's, have the same rate no matter where you go, which means that booking directly through the hotel site is the best bet because you can request things that the hotel may offer for free. In the case of Kimptons the have "tall" rooms, which means a longer bed and higher shower heads, something my husband loves, these can't be requested using another site. The other problem I ran into was checking on Hotwire; you don't actually get to see what hotel you will be staying at until AFTER you book the room. This is not for me, I like being able to see a picture of the room because if I have to spend a week in a overly modern space it makes me a little nuts.
The moral here is that it pays to do a little homework but I would suggest calling the hotel directly and ask if they can meet the rate you found on line and what comes with your room. Some hotels will even sign you up for their rewards programs which will entitle you to a free upgrade or other amenities.
I hope you all have a fantastic weekend!
