There's no weight prescribed because beginners don't have maxes for Snatch/Clean & Jerk and sometimes don't have maxes for BS/FS so it's more of a "go-by-feel" load. If your squat technique is fine then you can progress as you go.
The DLs aren't your traditional DLs. It's all Snatch/C&J DL so it's not necessarily a heavily loaded exercise for a beginner.
Is there no where for you to train on your trip?
If not, maybe you can do an abbreviated version of the program: Weeks 3, 4, 5 and then 7, 8, 9. Then when you come back from your trip do about the same thing or even go through to the end of the program so you can get back into it from the long break.
