Hi,
You can make a stop at any of the big towns like Ludhiana, Ambala for a decent stay.
In Patiala you have a "Moti Bagh palace" to visit and good street market for punjabi suits and juttis.
Chandigarh which is an hour detour but worth it
There is a "Gurudwara Shri Jyoti Saroop Sahib" at Fatehgarh Sahib on your way, but finding a decent hotel near it can be an issue.
Haweli in Jalandhar is also a good option.
