I'm asking for my brother, I posted about the marathon in November/room availability...The latest info is that its going to be a family of 5 trip with a car rental. The youngest is 18. The rest are are over 21. Are there any 'Must See' casinos off the beaten path...away from the strip/downtown? They are planning on driving to Hoover Dam and a trip to the south rim of the Grand Canyon; are there any recommended must see stops along the way to either place? I'm trying to give him the best options to plan for a Friday to Tues or Wed. trip. He'll be running Sunday evening.
