Ventajas
Working with parties means you get a lot of experience handling kids and parents, so communication skills really get built upon. At least in the location I worked at, you can make good money through tips since these party packages are expensive. It's a good side gig to make money as a student all things considered.
Desventajas
Management sucks. They don't really care to prioritize your party's needs which means parents get mad at you, and it's hard to deescalate. There's not good communication between management and the party host department, and they don't really care to include you in department discussions so you're always the last to know about new updates and changes. You might not get many hours since it depends on the booked parties.
