British self-help tour

I studied in England for a year, all of them traveled with a group, and some of them were good. My personal suggestion is to sign up for a self-help tour group (one week) to pick up the plane in London, because accommodation in London is very expensive and it is cost-effective to join the group. Then sign up for a tour group to go to northern Ireland, Scotland, because it's far away, it's more expensive to take a train and take a cruise. The travel company has arranged it. I'm so worried. I don't even know where to buy tickets for that flight. The rest is easy to say. One day in a city is enough. A day in Manchester, a day in Cambridge, a day in Oxford, and a nice manor in Sheffield, Darcy Manor in the movie. York is beautiful, with church, Betty afternoon tea and Harry Porterie Alley for a day. It is recommended to go in summer and spend a day or two at the seaside. If you stay, book it. It is recommended not to live too cheaply. Seventy pounds a night is the bottom line. Too cheap is neither good nor safe. Travel companies choose carefully. China travel agency is cheating people, so it's not convenient to explain here. I'm afraid it will seal my name. Please forgive me.
