A week or two is overkill. Playing almost every day is the best way to get better. There are, for many unknown reasons, problems that develop with playing that often. Some of it is fatigue (which is important to learn to play with) and some of it is getting into a mental rut (which is more important to learn to play with). The other thing is that you can learn many new skills so quickly that you have to, as they saying goes, take one step back to take two steps forward. Unless you push through you'll get into a continual rut of learning and forgetting and not improving.
So, take a day here and there, but if you want to get better leave it to that. Extended rests can be saved for the off season or for stormy weather.
