Is the tour of Omega Travel Agency fast? What is the frequency? I'm going to visit my sister in England in the middle of next month and take a trip.

Omega, as a relatively large travel agency in China, sends tours relatively quickly. Many routes were sent by Zhou Zhou. I have been to all the places you mentioned, including several routes in his home. As for which one to choose, it's up to you. However, there are many people traveling in the summer vacation, so it is recommended to register in advance.
