Yes, its loud - the train will come through a couple of times a night and shake the rig, and the traffic overhead is constant, but all in all we thought this was one of the nicest overnights we've had.
The seafood buffet was worth the price ($19.99) - lots of crablegs, shrimp, etc. It has over 1,600 slot machines, table games, and live games. The parking lot fills around you, so if you pull in and park, you are there until morning because you'll be blocked in for sure. The Golden Nugget is a large resort in Louisiana, USA. The view was fabulous of Lake Charles in the morning. We thought this was a fabulous stay - to pull in on New Year's Eve and get a spot, we'd guess you could get one any day of the year. The RV parking lot is not well signed - we first deviated toward truck parking, so when you come up to the casino, go straight through the stop sign, don't turn left toward truck parking. We were able to park right along the Lake in nearly the same spot as the previous reviewer shows in pictures.
The casino was packed, and the RV lot had a lot of employee cars.
