The hotel DOES NOT FREE WIFI, how can the Sheraton claim to be 4 stars but not have free wifi? My friend got the deal on this through Hotwire and we felt jipped that it said "free wifi" only to find out that it does NOT. The hotel is close to the airport but any decent food, shopping or things to do are quite far and require a car. The rooms are clean, nothing special about it though.
