My DD's 11th birthday is 3 mos away. Every year we do some extravagant party (with family and friends). They have been as follows: a catered party at a Horse Ranch, a Spa birthday at a full spa (2x), a catered tea party, a waterpark party, a party at a petting zoo, a party after taking everyone out to the movies, and a party at a gymnastics studio. Before she was 3, it was simple catered parties at a rented venue ... *sighs* Long story made not as long, my son just turned 4, and because his bday falls on NYE, we have always had smaller parties for him (which isn't fair but most people don't want to travel to us during the winter ... and it's New Year's eve, so everyone is either partied out OR has plans 😟). Anyway, we told DD that she could have a smaller party or get together this year but nothing super pricey or extravagant. She decided on a sleepover (ECK! I do not love this idea) with her 2 best friends and her cousin. She keeps changing themes ( Roblox to Unicorns to Spa) which is stressing me out as I can't fully plan without her definitive OK. Not knowing the theme, what activities should I include in her sleepover? I was thinking:
• Ordering supper out
• Letting the girls make and decorate (and eat) cookies or cupcakes
• Doing facials and nail painting with them
• Letting them play preteen/teen board games
• They can watch an approved movie.
... It just seems so boring!!!

What else can I include? And any suggestions for activities or items that would make this party low-key but FUN?
