Thanks for your reply!
I understand, we can have unacceptible delays on border or roads.
I am also considering Goung there by car so please share your experience.

Can you give me an idea how long it takes to reach Makkah by road?
Is there any parking facilties there ?
What kind of traffic i can expect on arrival in Makkah?
This is my first time and dont know arabic at all so dont want to get lost and waste time in asking people about directions, parking etc.
