The Silver & Turquoise Ball which is a signature event for the Phoenix Indian Center, has been held at the Scottsdale Resort since I've been going and most likely prior to 2013. The venue we use includes a courtyard, perfect for our silent auction event and cocktail hour before moving into the adjoining ballroom. I have never stayed as a guest so I can't speak to the additional amenities. Their staff has always been incredibly accommodating and each ball grows into a bigger event every year. I look forward to next years event.
