Hi! I have been. If you go, I wouldn't plan on staying there for any length of time though. There are casinos which are the main attraction, as well as the boardwalk on the beach, but besides that not too much else. One interesting aspect about Atlantic City is the fact that the streets, water company and electric company on the Monopoly Game were named after actual streets and businesses there, so if you want to explore and see what Marvin Gardens, Baltic Ave, etc. actually look like you have that option, But BEWARE if you do. Only take a taxi, and watch your back as there are a lot of not so nice ghettoey areas in AC, and with it comes lots of robberies, etc. Stay on the beaten path though and you should be fine.
A funny story. The last time my friend and I went, we spent some time on the boardwalk. There were lots of yummy treats being sold, salt water taffy, candy apples, typical carnival fare. In the candy shop, I saw some nice chocolate truffles. I bought a few, and as we were walking I decided to have one. I bit into it, and felt something strange brush my mustache. I thought to myself WTF? but didn't think too much about it. As I was chewing, savoring the unique flavor, I look down at the remaining half truffle in my fingers only to find a HALF of a worm squiggling inside of it! As I started gagging, I threw down the rest of the truffle as I ran to a garbage can to spit out the remainders of the worm infused, chocolatey morsel. My friend could have peed himself from laughing so hard. That was my final memory of Atlantic City!
Personally, I would try to find some other places in the area to visit. I would much rather go to the North Shore of Mass. Marblehead, MA is a nice, quaint town, and just a short drive from that is Salem, MA and other scenic, historic and fun filled towns.
If you do decide on AC, have fun, be safe, and DON'T eat the Truffles!!!
