The Tempe Mission Palms sold out quite quickly. Well within a week (first 2 days or so, I believe) of registration opening.

There's the Courtyard by Marriott that is about 3 blocks away that you will want to give a try, and soon. Because that's where they're referring folk now that the Mission Palms is sold out. So check there fast! Mission Palms also has a wait list you might as well try and get on as there will always be some people who reserve with intent to attend but end up dropping out as the event date nears.

I'll be staying at The Phoenician in Scottsdale, which is about 5-6 miles from the Mission Palms. But as I know my way around Phoenix well and have rented a car for my time there, I'm cool with staying at a hotel/resort other than the Mission Palms. Plus I don't drink so don't have to worry about driving back to my hotel after a party
