This was a Hotwire End of Summer Sale Hot Rate advertised by Hotwire as:
5 Star
Regularly $508 per night, on sale for $223 per night, saving 56% off of the regular rate
Fitness, Business, Internet
No where can I find where the Renaissance sells for $508 per night, so this was a huge let down. On their regular booking engine, Hotwire is currently selling this hotel for $246 per night, the direct Marriott rate is $209. Hotwire is advertising other hotels in the $500 range, such as De L'Europe for $508 per night, The Hotel Sofitel Legend for $530, The Andaz Amsteram Prinsenfracht for $477, etc.
I've been on the hold with Hotwire waiting for a manager for the last hour trying to resolve it, first customer service person did ask if I took a screen shot, unfortunately I did not. Now I know, before booking anything opaque, to take screen shots!
I hope this was a genuine mistake on Hotwire's part, not a bait and switch. Buyer beware!
I did book through the HOTWIRE link from this site, don't know if there is any tracking here that could help.
