I don't have a final guest list yet, but the kids vary from 4-8. There may be two boys, likely only one. And roughly 6-8 girls.
My initial favor thought was watercolor paints (Rapunzel paints in her tower) with a few small things to go with (snack or candy, tattoo or stickers).
My other thought is maybe some cute hair clips or elastic, a mini brush and a candy/snack (Rapunzel's hair!). Obviously I'd sub for the boys Maybe something to go along with the Snuggly Duckling crew (those ruffians!)
Here are some photos I had for inspiration..
