Winter parties for 2 yr old ??

HELP!! I have no idea what to do for our sons second birthday party! His party is in the first week of January, he will be 2. Last year we just did something inside since he was younger but now he’s into all kinds of things, I wanted to rent jump houses , but other moms with his friends are more “protective” than I am as to what they do or do an indoor one but that is super costly!! I need ideas. I want him to be able to play around and have fun and for the older kids to have fun also..

I’m about to just say screw it. We’re doing bouncy houses and if the other moms don’t want them to go outside to play then oh well.. lol
