As a party host I might be personally biased, but I think tipping really depends on how much the host has to do. If they’re not doing much (just bringing and serving food, cleaning up), don’t tip much (~$10-$15). But if they’re standing the whole party, running around and making sure you have everything, tip more (~$25-$30). My job as a party host was to do everything—set up, clean up, get food and drinks, give kids wristbands (I work at a jumping place). I also worked alone (the only host for a whole party). I walked them parents to the cashier and usually outside to help loading gifts. If you leave your party either saying “wow! I barely had to do anything. the host was great!” tip a lot. We do get paid minimum wage but we also work our asses off, and usually stay after we’re supposed to leave cleaning (I stayed back a whole extra hour today cleaning, which I wasn’t paid for since I wasn’t scheduled for it). Even if the host was just okay or you’re unsure, tip around $20. Definitely makes our day when we get a nice tip for hard work!
