Activity Station Planner Methodology
How the Activity Station Planner picks 3-5 stations for your age band, where the station recommendations come from, and how we keep the rotation math honest.

How We Recommend Stations
The planner takes the celebrant's age band, your space profile (tight, standard, roomy), your total station budget, and party length. It returns the recommended station count (3-5), the minutes per rotation, the total budget band, and a curated list of stations drawn from the age band's station pool — sorted by setup time (lowest-effort stations win the slot) and filtered by the budget cap.
Core recommendation logic
stationEligibility = duration_minutes 10-25 AND group_size_max >= 5
recommendedCount = { 3-4: 3, 5-8: 4, 9+: 5 } // 15-min-per-year heuristic
budgetCap = { free: $, low: $$, mid: $$$, high: $$$$ }
spaceFloor = tight ? max(3, count - 1) : count
usableMinutes = max(45, partyLength - 30) // 15 arrival + 15 cake/goodbye
rotationMinutes = floor(usableMinutes / count)Costs are quoted per-station as tier symbols ($/$$/$$$/$$$$) plus a total budget band per age. We don't multiply costs across stations because most parents reuse supplies (tape, markers, cardstock) — the totals reflect real party budgets observed across the Party Genius cohort, not naive per-station math.
The Seed-Data Footprint
Across Party Genius AI's 117-theme cohort, 1400+ activity rows are tagged with duration, group-size, and age range. Filtering by duration_minutes 10–25 AND group_size_max ≥ 5 isolates the station-eligible subset — activities that can run at a fixed station with kids cycling through. These map cleanly to the canonical 3-5 station recommendations per age band.
Assumptions & Defaults
| Variable | Default | Why |
|---|---|---|
| Attention span | ~15 min per year of age | Child-development consensus — used to set rotation cap by age band. Ages 3-4 = 10-15 min; ages 5-6 = 15-20 min; ages 7-8 = 20-25 min. |
| Station count | 3-5 stations | 3 for under-5 (fragmentation risk), 4 for ages 5-8 (the sweet spot), 5 for ages 9+ (longer attention support). |
| Station eligibility | duration 10-25 min, group_size_max ≥ 5 | Activities under 10 min create transition churn; over 25 min lose the rotation benefit. Group-size floor of 5 ensures a station handles a typical guest cohort. |
| Space per station | 5-16 sq ft (age-scaled) | A card-table footprint for toddlers (5-8 sq ft), elbow-room growth through tween parties (8-15), and zone footprints for teen activity bars (10-16). |
| Transition buffer | 30 min total per party | 15 min arrival + 15 min cake/goodbye. Subtracted from party length before computing rotation minutes per station. |
| Setup time | 3-25 min per station | Lowest-setup stations win when budget or space caps the count. Pre-cut materials reduce day-of-party stress more than fancier supplies. |
| Theme fit | 3-5 themes per station | Each station lists the strongest theme overlaps so parents can pull the decorations and props they've already bought for the theme. |

Edge Cases & Limitations
Mixed-age parties: the planner uses the celebrant's age. When older siblings or younger cousins are present, drop one station and add a free-play zone (bubbles, books, sensory bin) so the off-age group has a soft landing. Outdoor-only parties: the space profile of "roomy" assumes covered space — for outdoor-only, budget for shade and a rain plan; weather risk drops the recommended station count by one. Sleepover and 3+ hour parties: stations alone don't fill the time. Plan a movement break (dance song, outdoor sprint) every 60 minutes to reset energy.
Station-eligibility filtering is rule-based, not predictive — the rules surface the right shapes (cookie decorating, slime, photo booth, scavenger hunt) but the parent still picks which specific stations to run. The planner does not currently account for indoor/outdoor split, accessibility needs, or sensory-friendly variants.
