i am visiting downtown detroit this weekend. finally got some time off work. i don't drive and my trusty SMART route bus from metro has been eliminated on the days i plan to travel. arrrrrr. any recommended shuttles or taxis? i know the cost involved and how expensive it will be, but i am prepared for that. i just want some feedback on any service that is reliable and convenient. thanks for any responses. can't wait to hit the streets. merry xmas!!!!!!
