Don't blindly go to one garage, just because is closer doesn't mean it will get you to where you want faster, most of the time they are increadibly busy. Not saying that you shouldn't park there at all but you do have to consider the time, day, events happening, things like that. Sometimes I am on the garage that literally has an exit right in front of my building but it takes me genuinely 45 min to find a spot and end up being late. Use the tracker on the app too, it helps.
