Any Luck in NEGOTIATING room prices with Best Western East End?

They are giving us a block price of 149 per room.....however, fi you get a AAA rate, its only 135.15....

My guests are better off doing that....think I can negotiate with BW and be like, ummm..u give this for your AAA rate, but for l=like 10-15 people, guaranteeed...u give less?? HUH?!
