Wedding Day Getting Closer!!

Hi everyone- my wedding is about a month away (Jan 16, 2022) and I'm getting some pre-wedding jitters! Just want to make sure everything goes smoothly and as planned (I know it won't go perfectly but as long as there are no major hiccups I will be fine). I have absolutely every vendor scheduled and booked, flowers picked, decor bought, invites sent and our wedding is rather large (we currently have 180 RSVPed "yes" and still waiting on about 30 more). I think I'm getting nervous just due to the sheer number of people attending- my fiancé's family is huge. What should I be doing in this final month before the big day? Is there anything you forgot or didn't do that you wish you had? Any advice is welcome!!
