Best generic sorta advice would be to get there by about 3pm, and not plan to leave until after 2am. Last year I did the opposite...I left about 3pm and went back about 2am, and that worked fine, though Caesars garage was still claiming to be full at 2am and I couldn't get in, and the strip baracades were JUST coming down but I was still able to zip across the strip and park in Harrah's garage.

Don't know specifics about how far south the strip will close and whether you'll have access to Mandalay's parking (best bet would probably be access from Sinatra). Local news and the Review Journal generally publish specific street closing info a couple days prior to NYEve. And hopefully someone at Mandalay would know if/whether/when the streets around their place will be closed.
