You can visit Naldhera, Mashobra...Which is peaceful and perfect. At mall road it will be very crowded...of you love crowding places then its gud. Please make sure to book your hotel now...You won't find any place to live that time. Also, leave early morning on that day...cos the route will be overloaded and its under construction, to avoid any delay. It will take you almost 8-9 hours from Chandigarh if you leave near to lunch time.
