In general, we will arrange one hiking guide every 7 participants as below.
If you find the team members' physical conditions are very diverse (some are good at hiking and some have the very poor physical condition) in 3~7 person group, you might consider extra tour guide service. Because we can split the team into groups of two, each member can opt for the suitable group to meet his pace. Fast group does not need to wait for slow group and can get to the summit as scheduled without delay. The extra tour guide can accompany slow group in the rear and take care of them.
