Hi samibdr,
Well, according to Google, it is approximately 1 hour to Bern, 2.5 to Geneva, and 1.5 to Zürich. Traveling around Switzerland is not difficult without a GPS but you do have to pay attention to signs. Highways merge and split frequently around the big cities so just make sure you are always in the correct lane. The three cities you listed are all well-signed on the autobahn so I don't think you would have much trouble getting around. Traveling at night is also fine. Most of the highways here are great, though if you are going in or through mountains these roads are narrower with twists and turns. But they are still safe to drive at night.
Thank you for your reply

Could you tell me more about the weather? we are going to be in Brienz from the 17th of February to 24th of February.
Regards
Sami
