Ok so my daughter is turning one in October I need help tho

I know I wanna do a cake smash and have it colour themed pink purple and gold

I'm plan on doing a cake smash photo shoot before her birthday so I can use the photos for invites and also as decoration

My question is tho

Where would you hold a 1st birthday as me and my partner are staying with his mum and her house is tiny and tbh it isn't the best place I try have me and my partner and daughter stay with my family as much as possible as its a lot cleaner and just a nice place to be till we can afford to move out

I was thinking a park but most of the people there will be 18+ and won't really like that plus it will still be a tad cold as it will only just be Spring hear so where would you hold a first birthday and what good and activitys and stuff would you all have ??
