Choose between で (action) and に (existence) after a place
The particle で marks where an action happens, unlike に for existence.
JLPTN5
place + で (action) vs place + に (existence)~ de vs ~ ni
[place] + で = doing there / [place] + に = being there
Example Sentence

Transfer at the next station
Both で and に can follow a place, but they mean different things. Use で when something is being done there — the place hosts an action. Use に when something simply exists or stays there, with verbs of being and location. Choosing the wrong one changes the whole feel of the sentence.
