We are considering booking a trip to Niagara Falls this August. Planning on flying to Buffalo and staying at the Sheraton at the Falls. We are only going for a few days and so far, we want to go to the Falls, visit the Fashion Outlet Mall of Niagara Falls and the casino. A pretty basic quick trip over 4 days. Will we need a car to do the above listed things or can we get away with a shuttle from/to airport and cabs?
