I'll give you a little advice

1. If it is two people can self-help tour better, freedom of action, you can eat Beijing snacks while playing.

2. But if self-guided tour of more than four people I recommend with the group, more people also have more opinions, if more people, free travel is not good, the delay time days long, everyone has to take care of, but also the same opinion to be able to, this time you can follow the group, everything with the guide to go, the arrangements for unity, uniformity of action, the tour can be carried out smoothly.

3. If it is a large family, you can consider the independent group, so that the reputation of the better travel agency to give you a more satisfactory itinerary, the price is appropriate, the tourist attractions are also good, and then everyone according to this itinerary tourist activities

Now, such as the China Travel Service, China Travel Service, Shenzhou, the Youth Travel Service is a relatively large travel agency, it's not bad. However, some not very big travel agencies are also good, such as China Tang, the ocean, there are many good travel agencies you can check from the Internet, there are also some good travel sites, you can also refer to.
