Barbary / Bill's was at or near the top of the list. Small, 4-story hotel, nice, easy to navigate and no rat maze, cheap, fantastic location, mid Strip. Craps tables were the best with smartass but fun dealers. Harold may have been the best pit boss ever. Cocktail service was great. You'd hear Big E in the afternoon from the stage. And at night was the icing on the cake - Drais would open at midnight and those same crap tables were immediately next to the club's restrooms, specifically the women's restroom. At about 3A the parade to and from the restrooms became the show of all shows, all the while you're at a low-min table with constant cocktail service. It did not get any better.
Just got back from a 4-day stay. Across the board the Uber drivers, restaurant employees and casino workers were in unanimous agreement that the F-1 is destined to be a cluster. One pit guy we talked to at Paris said they have no idea how they're going to be able to drive in to work. Contemplating housing employees in the hotel out of necessity. Should be fun for them.
