The six flat detail rows become three meaningful buckets — Place & arrival, Guests & access, Look & feel. Half the things to scan; each opens to reveal its related fields together.
What are you planning?
The bet: fewer top-level choices lowers the "how much is this going to ask of me?" feeling. Place & arrival holds address + area + map + parking + dress + good-to-know; Guests & access holds reach + invites + a word for guests; Look & feel holds cover + theme + description. Trade-off: each open bucket is taller.
