get itchy feet	to get a burning sensation to change the place
have itchy feet	not being able to spent too much time in one place
get the travel bug	become addicted to travelling
culture vulture	a person who is a passionate of culture
catch some rays	is to sunbathe
sit and watch the world go by	have a moment to contemplate and not do anything
Pack a lot in/Have a full plate	is to be busy with the duties .../...
See how the mood takes me	Make decisions in the moment depending on how you're feeling
Travel on a shoestring	travel on a budget, not spend much money while travelling
live it up	is to spend one's time in an enjoyable way, travel in luxury
travel light	travel without much stuff
at the crack of dawn	early in the morning
watch your back	be careful in a new place
a culture shock	feel uncomfortable in a new place
