The people who are coming are going to be there because they love you and want to support you! They'll be happy to witness this important moment and probably catch up with you guys and other guests. You don't need to entertain them. It sounds like you have food covered and that's basically the biggest thing! It will be okay!!!

My advice is to make a game plan and tackle things in order. Start with the where. Then the when. Then the who. If you have close friends or family who can help with any of that, don't be afraid to reach out. And stay focused on the important part - you're getting married! Do you have an officiant? At the end of the day, people will show up, get fed, and get to see you get married!
