If you are coming by car, you have a few options.
Uber/Lyft: The easiest option will be to consider taking an uber/lyft to be dropped off and picked up at the front door.
Getting to 3 Light: The parking garage for Three Light is on Truman road between Walnut and Main. Heads up: If you use Google maps, it might suggest that the parking garage is actually on Walnut Street which is not correct.
Parking: When you pull into the parking garage, you'll take a ticket. Keep it with you, and ask to have it validated by the front desk receptionist. It will decrease the cost of parking to $6 upon exit.
The goal is to park close to the GRAY number 2 guest elevator. Take the elevator down to the ground level. Exit onto Truman and then enter the lobby. Note: The other elevators are for residents only.
Remember to Bring: A driver's license with you upon check in. This is a safety precaution, not a confirmation that you are of age to drink.
Arriving at the Party: Ask the front desk attendant to send you up to the 8th floor.
