The dress code is semi-formal. People will be in both long and short dresses so wear what you want! Men can wear either suits or tuxes-whichever they prefer!
Everything is walkable from the hotels listed on the site. The church is about a block away from the Read House and right across the street from the Westin. No need to worry about a car this weekend :)
The Westin and the Read House have valet parking. CitiPark Garage, a parking garage within walking distance of the hotels, offers 12$/day parking. The address is 802 Pine St Chattanooga, TN 37402. There is free parking by the church for the ceremony. You are able to leave your car at the church and walk to the reception but please no overnight parking as their church services Sunday morning start early.
Your ID (if you're over 21). TN will ID you every place every time if you order an alcoholic drink even if you're gray-haired with a cane.
Anyone who is a baptized Christian regardless of age is welcome to take communion at St. Paul's. You are also welcome to stay in your seat or cross your arms and come up for a blessing-whatever you prefer!
