I think to secure a couple of parents to provide help (in the kitchen/clearing up) during the whole weekend to free up the leaders so they can focus more on the kids (or grab a break)  without kitchen duty on top. 

My son said he would have liked a bit more quiet time, before bedtime. 

Also (at this age)to TELL the kids to wear something warm. My 9 year old thinks he knows it all but has come home really quite ill 🤦â€♀ï¸.  He had a fantastic time tho!
