Ah for that, you really don't have to show every detail of their journey, or write 'the protagonist left' or 'protagonist went to this place'.
The technique is, you can just show them in another place. Either you can write their new journey on another chapter, or in another scene. The reader would automatically interpret that as their group having travelled from this place to another.
Take a look at the early parts of this chapter from my work.
If you'd notice, the characters, Lily and Mariya, went around the small town job hunting. I did not write, "Lily and Mariya left and went to this place.", rather, I only gave clues that each of their job hunting failed (they'd gone to at least 24 different locations, without me telling the reader each and every location they went to).
And of course, if it's a failure, an applicant won't remain in that place for long. This is an automatic event, so your readers will just interpret it as is...unless you got something else in mind.
In effective story-writing, an author oy gives clues and lets their readers form their own pictures or scenes in mind. Don't spoonfeed every information.
Btw, pardon my replies. It may take a while, since I'm in my baking class.
Another technique:
I only put three 'examples' in my writing to show what's happening.
For example, if I wrote: "The mob is angry."
Then I'll give three angry dialogues to support what I wrote.
"Fuck off!"
"Resign, you incompetent shit!"
"Kick him off the throne!"
Any more than that is excessive and contributes to slowing the pace of your work. This principle can also be applied in shifting locations.
Always remember: Show, don't tell.
If I may add: Show the important parts. Tell the not-so-important parts.
Show: I stomped my feet and glared at the crowd.
Tell: I got angry at the crowd.
The idea of both statements are the same. But, for example 1, I showed my actions, and the reader can interpret those as I'm angry.
For example 2, I just told the reader straight, I'm angry.
'Show' passages give excitement and feelings to the reader, while 'Tell' simply says what's going on.
