The first time I participated in Ctrip's travel project, it involved places that Ctrip could control, such as the services of the order specialist from the beginning, and the tour design, hotel arrangement, vehicles and catering were satisfactory. Unfortunately, the UK's ground tour guide service is very general. This may not be all controlled by Trip.com, and it is mixed with the individual supervisor of the tour guide. But it does not affect the experience of the entire travel project very much. I will also participate in Trip.com's projects in the future. On the one hand, I will not encounter poor tour guides every time; On the other hand, with this experience, I trusted Trip.com's operating procedures.
