Engagement Picnic Party

Hello! Our engagement picnic party is in October. The setting is large pavilion shelter and a nice grass field. Most of the guests are 25 years old and then we'll have our middle aged families and some family friends. I'm planning to have lawn games out (Giant Jenga/Giant Tic Tac Toe/Giant Connect 4, Cornhole), a "Ring" Toss type area with either pumpkins or bottles, a Beer Pong Table, and a photo op area? And of course good food and drinks. Does anyone have other suggestions? I feel like that list covers good ground, but was just wondering if anyone had experienced something else that was really fun or really special in a similar setting? Thanks!
