Visitors will not need a guide at all times. Sometimes, they like to have a private experience. They would like to have the option to call on an interpreter or guide if needed. Here Roving interpretation is handy. The roving interpreter will rove with the group and will present information only when he approached. People sometimes know more about the tourist experience than the tourist guide themselves. They could be experts in the tourist situation they are having and will not require the services of the tourist guide. In such a case it so happens that a tourist guide would only probably get in the way of the tourist experience.
Presentations, form of interpretation, will be suitable for guest who would like to have some information on the tourist experience that they are about to have. This could be for children where interactive presentations could be made, or it could be for adults. It could be an optional choice for a tourist.
Demonstrations done with props or other settings would be useful interpretation in the context where young children or an easily bored audience is involved. Demonstrations can be simple enactments. For instance, where the tourists are going to visit a boating place, the guide can show how to latch lifejackets
