Every 1 year birthday I've been to has been at a park or somewhere outside.

Where I live it will be around 110 - 115 .. so ridiculously hot. We can't do it outside. Maybe a pool party but I still think people will think it's too hot.

I know it's a 1 year old so w/e but most people coming have 3-9 year olds so I want somewhere for their kids to play so people will come.

I'm already nervous enough that people won't want to come in early August.

Any ideas?
