I have been to the Flamingo numerous times. Here is my overall synopsis.
In terms of the room, it depends what room you get. The regular rooms are no frills 3 star hotel amenities. The bed cover is definitely not a duvet. The TV monitor is dated and so is everything else but if you don't mind this, it is decent. The Flamingo has GO rooms which have much better amenities such as a TV in the bathroom mirror, a Denon stereo system, a flat screen TV, and motorized window screens.
The casino is not really that great. If you are looking for the older crowd who is trying to save a buck by staying here, then this is a great place. I rather go to the other casinos on the strip where the people are younger. The games here typically are older than the ones on the strip.
I just ate at the Paradise Garden buffet earlier today. It was alright I suppose. What I really like about the buffet is that they have cocktail shrimp that is fully peeled. Most places do not peel their shrimp. There is a large variety of food but again, it is alright.
I have been to the pool before, the topless one but it is alright. It doesn't have the party scene like the other casinos on the strip. If you are an older person who is here to drink and smoke, this is a perfect place for you.
