What budget do you have for a 4 year old girls simple party with 15 friends.

Don't plan the party and ask for the budget. Instead, look at your budget and plan your party around it. A lot of party stuff are all just for the parents, kids don't need crazy things for their parties at all. As long as they have their friends, they're equally as happy just hanging out together at the beach or staying home and watching their favourite show together and have homecooked food + cake. If you're on a low budget, don't even look at parties over $100. There are so many places you can have parties at for free, no need for the fancy bouncy castles or buffet spread. You could even make simple games from recyclables under $10, they just need to be entertained and fed! If you can't afford anything, simply invite them to go for a get-together and inform the parents you'd help to cover ___, but they have to pay for the ____. For example, you can simply tell them no gifts needed but please help to cover their own children's meals. Parents are usually understanding because most of us are in this dilemma and tough spot too, and if they don't, you may not even need to invite those people to the party because birthdays/special occasions are meant to spend time together celebrating and NOT free entertainment for the other kids.
