PlanYourFun

Planning a bachelor or bachelorette party means three problems: nobody knows who owes what, nobody knows how much booze to buy, and the plan lives in a group chat where it dies. PlanYourFun is a free toolkit that solves all three. No sign-up, no app download, no paywall. **Cost Splitter** — Add everyone, log shared expenses as they happen, and see live balances. At the end it calculates the minimum number of transfers to settle up, so nobody sends five separate Venmo requests. Share one link and the whole group sees the same numbers. **Drink Calculator** — Enter guest count, hours, and how hard the group actually drinks. Get a real shopping list: bottles, mixers, ice, cups. Built to stop both classic failures — running dry at 11pm, or hauling home $200 of untouched White Claw. **Itinerary Builder** — Drag and drop activity blocks into your days, pulling from curated city activity lists. Share one link with the group, print it for the trip. The plan stops being 400 unread messages. **City guides** — Nashville, Scottsdale, Austin, Miami, and Las Vegas: what things actually cost, where to stay, what's worth booking. We also publish original cost research — our 2026 Bachelorette Cost Report breaks down real spend by group size and city, so you can set a budget before anyone books a flight. Built for the maid of honor, the best man, and everyone who got volunteered to organize this thing.
