What small details make an outdoor event more comfortable for guests?

I have been helping organize a few outdoor gatherings recently, and I noticed that guest comfort depends on many small details that are easy to overlook. Things like seating, lighting, weather planning, and facilities can really affect the overall experience.For larger events, I have seen people consider options like luxury portable restrooms to provide a more comfortable setup when permanent facilities are not available. What are some other things you think event organizers should plan ahead for to make outdoor occasions run smoothly?
