You're prob not going to find too many hotel options on such short notice, many/most are prob already booked.
But it really depends on your budget and with whom your travelling, if guys then you want W in Scottsdale, if wife/gf then just somewhere decent/nice in Scottsdale. Best nightlife, restaurants and WM open are all in Scottsdale, so that's where I'd look for a hotel.
Best of luck.
