My wife and I will be visiting Chicago next week and need to find a place to store a few small boxes from shopping while ice skating at Millennium Park in the evening, any ideas? It appears the lockers at the bike center are for long term members/renters only; I don’t really want to walk to Union Station or one of the other museums (Shedd, Science & Industry) for a short skating session. Are there any lockers at the rink itself or in the Metra Millennium Station? I thought about using a bag/coat check at a nearby hotel, any suggestions / insights on that idea? Also, any recommendations for the safest route back to the Blue Line after dark (around 8:00 p.m. on a weekday) from Millennium Park? I certainly appreciate your help, thank you.
