I think you should keep that style of writing, it gives the reader a better sensory experience, a sense of being there in the moment with you, as you said.
Where are you going after Portugal btw? Spain? Or somewhere outside the E.U? Or maybe don't answer that, keep publishing the travel stories as they come :)
I was just asking in case you needed some tips about Spain... Anyways, happy travels and may you discover more delicious cuisines :)
