How to organise large groups without losing anyone

The guide crosses on green. Half the group follows; the other half is stopped by the lights. The guide can keep speaking, but there is no longer one group: there are two. The problem is not volume. It is reaching that crossing without a plan to separate and regroup.

A large group is not a small group with more audio. Time, space, risk and the ability to recover from mistakes all change.

Separate three limits that are often confused

The legal limit. Each site or ordinance decides it. Venice limits accompanied tourist groups to 25 people; Girona sets 25 plus the guide with specific exceptions; the Alhambra has its own conditions. Rules change by place and date, so check them before selling the tour.

Operational capacity. This is how many people your team can count, move, support and evacuate on that route. It depends on crossings, stairs, toilets, accessibility, language, age, duration and available support. There is no universal maximum of 40 or 50.

Technical capacity. This is what the audio system supports on the actual device, network and route. It must be tested. A configured application limit or catalogue number does not prove a physical tour of that size works well.

In practice, the lowest of the three limits is the one that matters.

Design the route as a sequence of regrouping points

Walk the route at the real time of day and mark:

• ◆a start with space to explain the rules;
• ◆crossings, stairs, corners and narrow streets;
• ◆areas where the group must not block passage;
• ◆toilets, seats and water points;
• ◆accessible paths and step-free alternatives;
• ◆visible regrouping points;
• ◆an emergency exit and unmistakable finish.

Do not explain while the group is passing through a point that divides it. Cross first, count next, then speak. A brilliant story does not compensate for leaving eight people behind.

Assign roles, even with a two-person team

The guide leads, makes decisions and communicates. A sweeper confirms nobody is left behind and reports incidents. If the group needs a sweeper but only one professional is available, reduce its size, simplify the route or regroup more often. Asking a visitor to help with orientation may be useful, but it does not replace trained staff.

Decide how guide and sweeper communicate when audio is one-way. A message, call or agreed signal is better than discovering a problem at the next stop.

Count people at defined moments

Use a named list or subgroups at the start, after a critical crossing, following a break and at the end. Avoid asking “is everyone here?” because nobody can answer with certainty.

For late arrivals, set one place and time. Do not stop the whole group to rescue someone from an unknown street. Share instructions before departure and decide when it is no longer safe to admit another person.

Audio helps, but it does not manage space

A radioguide or phone-based system may let the last listener hear without the guide shouting. It cannot reveal a kerb, clear a narrow street or confirm that everyone crossed.

Test audio on the worst section with the planned group size. Check joining, batteries, earphones, interference and recovery after disconnection. Carry a simple fallback: stop, regroup and give essential instructions without the system.

Prepare accessibility and emergencies

Ask in advance about mobility, hearing, vision and cognitive needs. Ask about medical information only when the organisation has a lawful, safe procedure for handling it. Provide distance, gradient, steps, toilets, seating and duration before booking.

At the start, explain:

• ◆who leads and who sweeps;
• ◆which signal means stop;
• ◆what to do if someone loses the group;
• ◆where the tour ends;
• ◆how to request help immediately.

In an emergency, safety takes priority over finishing the story. Stop the audio, gather the group where safe and follow the venue or local emergency plan.

Rehearse before accepting maximum capacity

Run a trial with staff or volunteers. Time access, issuing or connection, movement, counts and closing. Note where the group stretches and how long regrouping takes. Increase size in stages; do not jump from a small test to the commercial maximum.

The Echoris prototype is intended to provide the local audio layer without dedicated receivers, but it does not replace this operational design. Before professional use, the route, phones, hotspot, duration and group size must be validated; there is currently no certified physical capacity. If a group is larger than you can move safely, splitting it remains the right answer.

Pre-departure checklist

• ◆local rules and capacity confirmed;
• ◆list or counting method ready;
• ◆route and accessible alternative checked;
• ◆sweeper assigned where necessary;
• ◆audio tested and no-audio fallback prepared;
• ◆late-arrival point defined;
• ◆emergency procedure and contacts clear;
• ◆finish communicated.

The goal is not to take the largest possible group. It is for every person to arrive, understand and finish together.
