That holiday Inn is a little ghetto if you ask me
But I had a great time while I was there, no problems, no hassles. You can literally walk to the stadium from there or take a 2 dollar cab ride if it's too hot to walk. It's in a bad neighborhood, but the Holiday Inn's location is seperated from the area. The crack problem is very real, however you would have to literally venture into the neighborhood and into the projects to get something. Trust me that Holiday Inn has been there for years and aside from the occasional teen parties that they have there in the ballroom, you rarely see neighborhood folk venture into the hotel area, unless they work there.
You can find nicer more pricier hotels by the airport and on South Beach, but even there you can get robbed or your room broken into, or jumped by drunk idiots, especially on South Beach.
I personally would stay on the beach because there's more to do, more to eat, and more people to meet, and the area where the Holiday in is located is close to a few fast food joints and a big a$$ ghetto a$$ flea market and that's it aside from some great Jamaican restaraunts around there. There's nothing to offer, except it's close proximity to the stadium. The biggest hassle of staying on the beach though, b4 and after the game, the traffic sucks, but that's a small price to pay.
