First time staying downtown in Vegas - advice

Hey - my wife and I are going to Vegas and going to stay downtown for the first time - staying at the Golden Nugget because they have a special where you pay for 2 nights and get the third free - so we are spending a total of $150 for 3 nights.

Just wanted to get some thoughts and advice. We usually stay on the strip when we go to Vegas, but this time we are trying to keep our costs as low as possible - also, my wife LOVES the bingo and that's all downtown.
