Planning a 3-day trip to Indore – Need Suggestions

Hi everyone, We are traveling from Hyderabad to Indore for a 3-day trip. The main purpose of our visit is to have darshan at Mahakaleshwar Temple in Ujjain and Omkareshwar. We would love recommendations on other must-visit places around Indore, Ujjain, and Omkareshwar that we can cover in our itinerary. Additionally, does anyone know if we can get Bhasma Aarti tickets on the spot, or do we need to book in advance? It would also be helpful if anyone could suggest reliable tour and travel operators for transportation. Thanks in advance!
