We did 3 and a bit weeks in August. Yes, it was great BUT it took a huge chunk of our annual leave at work. This year we have decided on two 10 day breaks taking in bank holidays to save annual leave. We loved the three weeks but we began to feel like residents there and it sort of lost its holiday feel. Each to their own of course but whilst we are working to limited annual leave entitlement, I suspect we won't be doing three weeks again.....
