Review for Casino Grand Prix - Vana Review For Casino Grand Prix - Vana Google User Oct 13 '17 at 23:32 Mandalay Bay convention center really has a wide variety of spaces to utilize for conferences. Just attended a 15k person conference there and the variety of rooms really was tremendous. Staff were very lovely to interact with. The only thing that really could be a con, is just the sheer size of the center made it take a while to get around sometimes. And also, some of their rooms can be a bit difficult to find. Very labyrinth-like in some ways. But overall a great experience, even just a week after the tragic shooting that just took place there. View full site to comment or like
