Travel / Good Idea? Travelling by car near Poland's Tatra mountains? [2]

We are thinking to hire a car to travel around Poland, probably we drive down to
the south part near the mountain. Only 3days rental and hire the car from Krakow.

Would you recommend resasonable car rental company?

Wondering if it is easier to drive and the best to take the car to travel
in Poland. Any suggestion how to travel near the Tatra mountains, Zakopane?

Thank you very much in advance for all your kind answers.

What is happening during the Easter time in Krakow? We stay in Krakow and plan to do some sightseeing as well. Does the shop close on Easter Monday? Any exciting event in the city centre? Thanks...
