The green arrows indicate the 2 entrances into 12th Place Complex. The black indicates where temporary fencing has gone up for construction where no cars can go through. Please follow the purple routes to get to our room entrances. The red star indicates our back entrance which will now be accessible for guests.

We are located in the back NW corner next to Shading Concepts and underneath Healthy Paws.
