Hyderabad to Meghalaya Road Trip

We are a family with two kids and would like to travel to Meghalaya from hyderabad on road...we are looking for people to join us in this road trip..
If there are two people they can travel in our car and if anyone wishes to bring their car we can travel in a convoy and that would be fine.
No strict dead lines but only agenda is to start in the last week of may and return before the summer holidays end for kids...open to suggestions ..once everyone agrees we can start. I have more than 22 years of experience in driving and have driven more than 2 lakh kms till now in different cars.
