Just like the world and even state to state, each area is handling COVID-19 a little differently. Make sure you add to your website or invitation what precautions are needed. With the sheer amount of changes that are happening and how fast, having a whole page dedicated to COVID-19 questions would be the best option. Make sure to include information on what precautions are expected at your venue and the area you will be staying in. Having a link on that page to the local government would be another great way for your guests to keep tabs on the changes as they get closer to the date of your wedding.
