Try a public space like a community center or t recreational hall
I stressed about mine for ever till I called the church by my house and they actually rent their meeting hall I'm paying 375 from 5 to 11 and I'm having over 120 guest .. Definetly the cheapest
call local resorts !
$100 its really cheap! But not worth it if you are gonna spend more money making your baby shower and not getting what you want.
Have you called hotels and asked about their conference rooms? Or maybe call your local chamber of commerce and ask if they have anything or any suggestions.
