I think there's a whole debate about this going on, and there's really no advice to give.
A good description can be something really vague or a ultra-detailed scenario. It really depends on how you put it, a good, detailed description is not twenty lines long, you can group a good scene within a line or two. And also, depends on your writing style and how you feel more comfortable, while keeping a good flow in the story and not jumping from point A to point B suddenly.
But when there really is no other choice, I see no problem in describing characters walking from a point to other in complete silence, while describing the place in which they walk.
Good luck with your work bro!!!
