Private tours and tours are two different ways to travel, and they differ significantly in a number of ways. First of all, private tours are usually organized by consumers themselves or booked through a small number of people, so they are relatively small. In contrast, tour groups are organized by travel agencies or ** travel platforms, and are relatively large, usually including dozens or even hundreds of people. Secondly, the itinerary of private tours is more flexible and can be customized according to the needs and interests of consumers. Tours are more fixed itineraries and usually include a predetermined list of attractions and activities, which travelers need to follow according to the itinerary. 
In addition, the quality of service for private tours is comparatively higher, as private tours are usually served by professional travel agencies or tour guides, who pay more attention to customer experience and satisfaction. There may be some problems in the tour group, such as the lack of detailed explanation of scenic spots, unreasonable itinerary, etc. In addition, the ** of a private tour is relatively high because its service is more personalized and requires more fees. Tours are relatively low, as they can reduce costs through high sourcing and economies of scale. 
Finally, private tour travelers are often more focused on travel experience and quality, so private tours often offer more high-end hotel and dining experiences. Travelers in tour groups may be more budget-friendly and practical, so tour groups often offer more basic accommodation and meal services. In conclusion, private groups and tour groups are two different ways to travel, and there are clear differences between them in terms of size, itinerary, service quality, ** and passenger experience. Consumers can choose the travel method that suits them according to their needs and interests.
