Yes! Note that there is significant construction on I-94 underway. This may slow down your drive there. So please add in some extra travel time to account for this. There is parking on site. But Uber/Lyft are also good options especially if you'll be having a couple of drinks!
Yes, there is!
PAIKKA is located in the back corner of the building. If the weather is nice (fingers crossed!) the ceremony will be outside. You can go down the alley to the right of the building. If the weather is rainy, then you can get there through the building, walking down the hallway all the way to the back of the building.
