I will be going to WDW this spring,staying at All Star resorts.....I would like to visit other areas off the disney property, and would like to access a Walmart for groceries etc when I arrive.I will not have a car, and wondered if there are any areas nearby which can be reached by walking, or bus or taxi...also any idea how much the taxi fares are to these areas. Also, if there is a city transit system available.
