Now this whole section will sort of depend on the style your going for, for example, if your having a themed sleepover you could skip this chapter. You  Remember this is a list to consider some. I do not recomend to do everything on the list. 

Active  Activites:

• Pool


• Theme Park in your Area


• Trampoline Park


• Skating Rink


• Watch a Sport in Person


• Day on the Lake


• Spa

Chill Activites:

• Party Games


• Play in your Backyard 


• Crafts


• Fidget Trade


• Movie


• Midnight Feast


• Pinata

I realised while making this section I'm not good at making up ideas for party activites! I would put like junk food but thats not exactly an activite. Anyway those are just a few suggestions, I promise the next one will have more ideas.
