Priority Club is offering 500 points and a second night free at a new property in Shanghai for answering a few quick questions about what’s important to you in a hotel and how often you have traveled/will travel to Shanghai.

Terms and Conditions say the second night free is valid only for the first 500 respondents, but otherwise don’t seem to limit the offer in any way. They don’t say the survey is targeted, just that the offer expires December 31. And while these sorts of things are always “your mileage may vary,” I’ve found the Priority Club surveys in the past to be pretty good about posting points (after 6 to 8 weeks).
