Everyone knows I love Aldi, and have been anticipating the opening of the Baum Blvd. Aldi for over a year.
I have to admit the parking situation is a bit scary, but once you get over the initial shock of cars going up and down sharing the same ramp, you'll be fine. Parking in that area of town is a must, so I can deal with the slightly-scary parking garage. It is well-monitored by staff.
You don't have to take a cart from the garage if you don't want to; there are carts available at the front of the store (Baum Blvd. entrance). This Aldi is laid out like the rest of them; however, if you're coming off the elevator or steps from the parking garage, walk past the registers to start at the "beginning" of the store. Or you can start at the "end" and be a rebel.
Aldi has a much easier interior to navigate than it's more expensive counter-part one block away. Having that counter-part close is a bonus, though, b/c try as I might, I just can't get everything I need at Aldi. I usually spend the same amount at both places, and get twice as many goodies at Aldi!
Remember that Aldi doesn't take credit cards, it's cash, EBT, or debit cards, only.
