Choose a format by asking how guests will arrive, how much guidance they need, and what your host team can realistically support. Each option can work well when the session design fits its strengths.
Compare the main options
| Format | Guest experience | Host preparation | Watch for |
|---|---|---|---|
| Small group | One shared start and finish, with time for conversation and supported practice. | Confirm group size, seating, materials, and a host who can hear questions. | A discussion may run long; keep one optional element ready to shorten. |
| Drop-in | Visitors join when convenient and take part in a self-contained activity. | Prepare repeatable instructions, a visible welcome point, and enough materials for changing attendance. | Guests may miss context; make each activity understandable on its own. |
| Guided session | A host leads a sequence with a shared theme and planned transitions. | Write a simple run sheet, prepare the welcome, and agree who supports the group. | A rigid schedule can crowd out curiosity; allow room to adapt. |
Small group: make conversation the engine
Choose this format when your purpose depends on participants comparing observations, practising a skill, or building an idea together. Set a group size that leaves people room to contribute. A circle or shared table can help, though the right arrangement depends on the activity and access needs.
Build in a low-pressure opening question and one pair activity before inviting full-group responses. If the event is oversubscribed, consider an additional session rather than silently making the activity too crowded to work.
Drop-in: make every entry point clear
A drop-in is useful for community events, open houses, or visitors with varied schedules. Design an activity that can start at any point in a short cycle. Place the instructions where people can see them, and have a host available to welcome late arrivals without restarting the whole experience.
Use a repeated prompt, such as choosing a detail in a sky image and describing it. Keep supply replenishment simple and display the activity’s approximate duration so guests can decide whether to join.
Guided session: lead without over-directing
Use a guided format when guests benefit from a common sequence: welcome, short introduction, observation or model, discussion, and close. Tell people at the beginning what the route will be. A co-host can keep an eye on practical needs while the lead host facilitates.
Choose the format that makes your purpose easiest to experience—not the one that sounds most impressive.
Make the decision
Consider venue capacity, arrival patterns, host confidence, available time, and whether the core activity works for people who arrive late. If the choice still feels uncertain, start with a small, guided session. It is easier to learn from a well-observed pilot than to overbuild a complex event.
