Please accept my apology if you find my personal experience too offensive.
I won't and can't put 5 star and Flagship, Atlantic City together.
I bought Gateway from II for $195 for a week about 3 years ago (when Isabelle hit Delaware).
Atlantic city is run down and not very safe. Casinos charged $7 for parking. Buffet was terrible. There was minimal traffic in the casino.
Flagship is not a resort, but a converted highrise. The unit I stayed in for a week was spacious but full of smell like cat urine. The swimming pool and the spa are huge, but with a feel of cheap community centre. The whole building was dirty and poorly maintained, except the sales floor.
There were 2 things to remember though:
1. Miss American was held in Atlantic City. I watched the parade - the girls were terrific.
2. Watching big waves caused by Isabelle from the 17th floor balcony was exciting.
For sure, I will not return to both Atlantic City and Flatship.
