In your opinion, what is the best casino/hotel downtown...

I've stayed at Downtown Grand, Golden Nugget Rush Tower, and Golden Gate Suites. They are all top notch. I couldn't decide on room quality so I'd have to move to another criteria to make a decision.

Downtown Grand has hands down the best pool area if only for the fact that it's not packed to the gills with people fighting for a lounger.

Golden Gate has the most happening yet intimate casino floors IMHO. Also very cool to be three big steps from the hotel elevator to the casino floor.

Golden Nugget has the best amenities if you are an "everything under one roof" kinda guy and want the resort experience.
