Will you need a designated driver throughout the day? Maybe have a close friend or family member volunteer to drive you from spot to spot so you don’t have to stress about that.
Allow any vendors (probs your photographer!) to help you along with planning and executing this. The point of a courthouse elopement is to keep the stress levels low, so don’t be afraid to delegate tasks to your MoH, photog, or anyone else that can help you move through the day completely stress free.
Most importantly, you CAN still make this day just as special as any other wedding. Get a fab dress or suit, order a beautiful bouquet from your favorite florist, and maybe invite a few friends to get ready with you at the hotel. Heck, you can still have a small wedding party if you want! So much of this day can still mirror a lot of the “special” parts of having a big wedding, without the stress of managing a larger group of people.
