The first time I came to the UK, I felt that the route, tour guide and leader of this group were good. The standardized service of Trip.com was quite in place. It was in the ninth district of London. It was too far away. I could n’t find it on the map. Every subway ticket was 11 pounds, expensive! However, I still trust Trip.com , and I will participate in the group of Trip.com if I have the opportunity.
