Costco Hyatt Summer Discount: 10% Off and Third Night Free

For the past couple summers, Costco has teamed up with Hyatt to provide their members with solid discounts. This year the offer is 10% off and the third night free for stays 3 days or longer.
"Enjoy 10% off the Hyatt Daily Rate plus your third night free at participating Hyatt Hotels & Resorts in the U.S., Canada and Caribbean from May 16, 2011, through September 6, 2011. Or choose Hyatt Place or Hyatt Summerfield Suites and take advantage of 10% off the Hyatt Daily Rate and an additional 50% off the third night. The free night or additional 50% discount will be deducted at checkout.

Reserve now or call 877 849 2730 and request offer code COSTCO."

I priced this out and it can definitely save you money if you have 3+ day stays, however it won't tell you the final price without the third night since that is deducted at checkout. However, if you have super-cheap corporate codes, it may make sense to use them instead. In the end, I recommend playing around with the rates online to see which deal is better. Costco membership is $50, but people have reported using the rate without ever being asked for ID. I won't delve into the ethics of doing such a thing, so my advice is to only use rates that you are qualified to use.

Remember, Hyatt also has the Great 10k promotion until June 30 and the Costco rates are eligible rates - even if you get the third free, it will count towards promotion qualification.
