BYOB & Ice Planner

BYOB on a party bus saves real money — a $200 bar tab at a venue becomes $40–$60 of grocery-store drinks — but only if you bring the right quantities. Run out of ice in hour two and the night unravels fast. This planner translates guest count, ride length, and drink preferences into a complete shopping list: case counts, ice in pounds, cooler sizes, and the small items (cups, openers, trash bags) that experienced planners never forget but first-timers always do.

Default per-person consumption assumes social drinking pace (around 1.5 drinks per hour for cocktails or seltzers, slightly higher for beer). Adjust upward for celebratory groups (bachelor parties, 21st birthdays) and downward for older or mixed-age groups. Ice math is the part most planners underestimate — plan for 1–1.5 pounds per cooler-hour, more on hot summer rides where ice melts roughly twice as fast and the bus AC is fighting both passengers and direct sun.

Confirm BYOB rules with the operator before the day-of. Most party-bus operators allow beer and wine for 21+ guests but prohibit hard liquor or glass containers, and policies vary significantly by state and venue. Skip this tool entirely if your itinerary includes venues that strictly enforce no-outside-alcohol policies — the grocery-store savings disappear once you cannot bring drinks inside the bus. For tailgates, also check stadium-lot BYOB rules.
