Profbac,
I went on the Google earth web site and typed in 129 E. Fremont St. Las Vegas, NV 89101 (Golden Nuggets address) and looked at the over head view.
You can see where the Golden Gate and Four Queens hotel rooms pretty much go right out to the edge of the Fremont street and you can understand why the rooms are so noisy.
Then I looked at the Golden Nuggets hotels, which are behind the casino. The casino borders the Fremont street and the noise. The depth of the casino should keep you from most of the noise.
I am sure you can get a noisy room, but your chances are greatly reduced at the nugget from other casinos on Fremont Street. Again, if you simply ask at the check in counter to be away from any potential Fremont street noise, I am sure they will hook you up.
I have already booked the Nugget for late may and earl June, so let us know your findings (please)
