Going to Blackhawk in June and staying at Ameristar. Looks like there are several casinos in near proximity to each other. Can anyone tell me if they are walking distance? Trying to determine if we need to rent a car or just Uber from Denver airport and be able to walk to the other casinos. Car rentals prices seem high right now so if we don't need one we don't want to waste the money. Staying 3 nights and the rental prices are greater than uber to/from the airport.
