I travelled 1.5hrs to get home, and I am very glad I did .. I was in great pain I wont lie, but to be fair I dont remember the car journey.. but I remeber the relief of getting in my own bed. The next day was by far the worst day for me due to being sick with the anesthetic so very glad I was at home. I personally think 2.5hrs you will be fine.. worse to travel the next day.. just take yr pillow with you and water and yourl prob sleep xx
