Start from travelling teams, not total registrations. A 60-team tournament where 40 teams travel is a 40-team housing problem; local teams sleep in their own beds no matter what you contract.
The roster math
Each travelling youth team brings roughly its roster in families, minus carpools and minus the families who share. Occupancy runs high in this niche — siblings, teammates doubling up, a coach's family — often two and a half to three and a half people per room, the highest of any event type. A 14-player roster typically lands somewhere around 9 to 12 rooms once sharing is accounted for.
Multiply travelling teams by rooms-per-team, then by nights — and be honest about the nights. A weekend tournament is usually a two-night stay, but a soft Sunday night is exactly where night-by-night attrition measurement hurts you. Block the nights families actually stay, not the full span of the event.
Why tournament blocks under-report demand
Families are the most block-averse audience in events. They compare prices, they want kitchens, and four families will take a house over eight hotel rooms every time. Your pickup report only sees the families who used the link, so a tournament can fill every bed within ten miles while the block shows 55% pickup. The demand was real; the block just measured a fraction of it.
Practical sizing
- Contract 10 to 20% under your roster math — hotels extend filling blocks on a phone call.
- Prefer cumulative pickup measurement over night-by-night, and ask for a resell credit.
- Offer the families who skip the block a real alternative — homes, rentals, and nearby options on your confirmation page — instead of pretending everyone books hotels.
Tournament directors who treat the block as one channel among several stop fighting their own families, stop eating attrition on rooms that were never going to fill, and — with the right setup — earn on the majority who book outside it.
A worked tournament weekend
A 48-team tournament where 30 teams travel: at roughly 10 rooms per travelling team after sharing, that is about 300 rooms of demand for the peak night — far beyond what any single property will block for a first-year event. The workable structure is layered: a 60-room contracted base at the headquarters hotel for teams that want the official option, courtesy holds of 20 to 30 rooms at two overflow properties, and a bookable stays page carrying homes and rentals for the family groups, linked from every registration confirmation. The base fills safely past its threshold because it is deliberately small; the overflow layer absorbs the variance; and the families who want kitchens book houses through a page the event earns on instead of scattering to rental sites.
Contrast that with the common failure: one 250-room block at one property, signed against the full roster math, followed by a season of pleading emails and an attrition bill when 40% of families booked rentals — exactly as they always do.
Numbers to gather before sizing
- Travelling teams, not registered teams — check last year's roster addresses if you have them.
- Rooms per team from actual history: your sport's sharing culture, not a generic figure.
- The nights that actually fill — many weekend tournaments are one-night stays for half the field.
- The house share: what fraction of families booked rentals last year? That share will not use any block you sign.
