Yes, I thought it was a great price as well, especially since it includes 10 nights of valet parking. Most of the other hotels in the area are around $100/night with 7 days of parking which would leave us paying another 3 days parking rates at $11/day, which pretty much brings us to the rate for the Westin. The convenience of not having to go out into the cold February weather with no coat on (since we definitely won't be dragging our winter coats with us) upon drop off and return to the airport is also a big plus in my eyes!
In case anyone wants to look into booking this, you have to go into "Hotel Offers" on the site and then "Park for a Penny". If you just go through the main reservation area the "Parking Package" rate is higher.
