The four capacity models

Every activity picks one of four models on its Capacity tab:

• Unlimited — every timeslot sells without a cap, no seats to track at all. Built for things like a self-guided tour or a large open venue — picture a "Shakespeare in the Park" show, where there's no real headcount ceiling to enforce.
• Per ticket type, per timeslot — each ticket type gets its own seat pool. Right for an activity where different tickets genuinely have different limits, like a wine tasting with 20 General seats but only 4 VIP seats at the tasting bar.
• Per timeslot — one shared pool, no matter which ticket type fills it. Right for a vehicle or vessel with a fixed number of seats, like a boat or van tour — 20 seats are 20 seats, whether they're filled by Adults, Children, or a group rate.
• By resources — capacity driven by what you physically have, not a number you choose — a kayak rental limited by how many kayaks you own, or an ATV tour limited by how many vehicles and guides you have that day.

Per ticket type, per timeslot

Each ticket type gets its own real seat pool per timeslot, independent of the others — a workshop can offer 15 open Observer spots but only 6 hands-on Participant spots, and neither competes with the other for room.

Per timeslot and channel limits

If you sell through your own website plus resellers like Viator or Expedia, channel limits let you hold part of the shared pool back — capping what your website or your reseller partners can sell, below the total.

By resources and overbooking

By resources pulls its capacity straight from your Resources tab, so it only works once resources are actually set up there. And no matter which of the four models you use, one switch — Allow team members to overbook — decides whether your staff can still book a guest in after a timeslot shows sold out. Guests booking online can never overbook; only your team can make that call.

Resource pooling rules

Resources themselves are far more powerful than a simple headcount. A rental can require a boat and a guide together, or accept either a boat or a guide, whichever has room — real rules, built once, reused every time that ticket type is booked.

Packing strategies

When more than one resource could take a booking, you decide how they fill. Pack each one to capacity before opening the next — efficient, minimal wasted seats. Or keep a family or group together on the same resource, even if that leaves a seat empty elsewhere — the setting for something like a helicopter tour, where splitting a party in two would be a real problem.
