I stayed here during my business trip and frankly, it was better than I expected.
The hotel is huge and the check in line takes forever. It took me an hour. When my boss checked in in the evening, it took her an hour too! My room was very clean and had some cute pink curtains and a pink throw. The room and bathroom were very spacious. The thing I liked the most was the floor- it was a dark brown and foamy which is perfect after walking around all day in heels!
I liked all the pink touches and the flamingos in this hotel! Very cute.
I've heard good things about the pool but I didn't have time to check it out. It's got a great location in the middle of the strip and the monorail is a really short convenient walk away.
Let me put it this way: Flamingo is no 5-star hotel but for it's price and 3-star status and compared to other hotels of its caliber, I think it's great and I would totally stay here again!
