going from Madinah to Makkah in Umrah

Thanks!
We will get to Jeddah in the evevning. and there are no flights that night and and i dont want to stay in Jeddah. Also, I have been told that flights get cancelled very often? is that true?
So i am going to hire taxi. from Madinah to Makkah i have to decide if i want a bus or taxi (which one is better with a 2 year old kid as well? ) i dont know if he will be easier in bus…
