We booked the Hampton Inn at 13th and Race. It's not RIGHT in the Art Museum area, but it's $129 a night plus free breakfast for all in the AM....Not sure if when makes a difference, but we're the weekend after Memorial Day. I just did hotels.com and Windsor Suites (think it used to be The Wyndham) was $159 for a block of 8 on 31 May. Go ahead and tell the group sales folks that you got quoted $129 at Hampton for 20 rooms. Can't hurt to mention the competition. Good luck!
