The most common way a group loses an hour at a sacred site is at the gate. A client in shorts at the Grand Palace, a guest without a sarong at a Balinese temple — neither is an incident, but either can hold up a coach and embarrass a client in front of forty colleagues.
The four destinations do not share one rule. Each sets the line in a different place, and the briefing works only when it says which rule applies where.
Thailand: The Strictest Gate
At the Grand Palace and Wat Phra Kaew in Bangkok, visitors are expected to cover shoulders and knees, and the check happens at the entrance. Shorts, sleeveless tops and see-through clothing are the usual refusals. Shoes come off before entering the chapel of the Emerald Buddha, and photography is not allowed inside it.
Other temples in Thailand are usually less formal at the gate but expect the same standard inside: covered shoulders and knees, shoes off in the halls, and feet never pointed towards an image of the Buddha. The simplest rule for a Bangkok day is to dress for the palace and be correct everywhere else.

Indonesia: The Sarong Is the Ticket
In Bali, a sarong and a sash are required to enter a temple, and many temples lend or rent them at the entrance. For a group, carrying its own is faster and avoids the queue. Many Balinese temples also post a request that women who are menstruating do not enter; it is a religious rule rather than a courtesy, and the briefing should state it plainly and privately rather than leave it to a sign.
Temples in Indonesia are working places of worship, and ceremonies take precedence over visits. A ceremony in progress may close an area or change the route; that is part of the experience, not a failure of the programme.

Japan: Few Rules at the Gate, Many Inside
Shrines and temples in Japan rarely have a formal dress code. The etiquette sits elsewhere: rinsing hands at the purification basin, bowing at the torii, not walking in the centre of the approach, and removing shoes where the floor changes to tatami or wood. Photography is often prohibited inside halls, and the signs are not always in English.
For groups, the recurring issue is noise and space rather than dress. A large party moving through a small temple garden changes the place for everyone else, which is why splitting into smaller units with a guide each works better than one long line.

Korea: The Temple Stay
In Korea, the distinctive product is the Templestay programme, through which visitors stay overnight in a Buddhist monastery and join its routine. Participants usually wear the clothing the temple provides, remove shoes in the halls, keep quiet in the living quarters and take part in an early-morning service. It suits groups who want depth over sightseeing, and it rewards a briefing that sets expectations about the hour and the silence.

One Briefing, Four Rules
Write the dress and conduct rule into the day, not into a general etiquette page the client will not reread. Name the site, the requirement and the consequence: "Grand Palace — shoulders and knees covered or entry is refused." A rule attached to a place is followed; a rule attached to a country is forgotten by the second day.
Frequently Asked Questions
Can clients buy cover-ups at the Grand Palace? Vendors near the palace sell them, but relying on that turns a schedule into a shopping stop. Brief it the night before.
Do Japanese shrines require covered shoulders? There is rarely a formal rule, but modest clothing is appropriate, and shoes come off wherever the floor changes.
Is the menstruation rule in Bali enforced? It is a religious request posted at many temples. Brief it respectfully and let clients decide; do not leave it to be discovered at the gate.
Is a Templestay suitable for a whole incentive group? For a smaller subset, usually. The early start and the silence suit clients who choose it rather than those sent on it.
