Fun things for a sleepover:
Movie night! Have a ton of snacks and choose a movie everyone will love!
Game night! Ask everyone to bring a game, whether it's a deck of cards, Monopoly, or something new!
Spa night! Face masks, nail painting, robes and slippers, foot spas with salt or other things!
Just some different ideas, best answer would really help!
