So... I just booked at room at Bally's from November 11-15 to take advantage of a slot tournament that week-end at the Rio and to celebrate my birthday. Vegas is my "happy" place so Happy Birthday to me. Then I found out it is also the weekend of the Rock and Roll Marathon. Has anybody been in Vegas when the Marathon was going on? Just wondering if this is something fun to watch or more of a pain in the ass with lots of extra people in town.
