Composition of tourism products. Who can explain to me in detail what is the core part, morphological part, extension or additional part of tourism products? And demonstrate with examples.

All tourism products are composed of core part, form part and extension part. The basic utility and value of the core part to meet the needs of consumers is the theme part of tourists' purchase and consumption. Morphological part refers to the entity and shape that constitute the product. Extension refers to the convenience and additional benefits brought to consumers with the sales and use of products. Taking a theme park as an example, the core products of the theme park include excitement and atmosphere, and the formal products include brand, exciting amusement items, safety, service quality, amusement items and attractions in the park, service quality, and sharing the park with others. Extended products include opening hours, parking lots and services for tourists with special requirements.

However, there are many books that explain this in detail. We are all people who don't like reading! ! !
