As I did last year I highly recommend Eastside Cannery on the Boulder Strip - about 10-15 min drive to NAB. Super clean and nice rooms for around $59 per night. I've stayed there several times and love it. Though I did stay at Vdara last year and that was fantastic.
If you don't care about staying on the Strip Eastside Cannery has great buffet/restaurants/bars at old school Vegas prices.
