Hi all! I'm heading off on my much anticipated vacation two weeks from today! I had a quick question. I am planning to take a coach from the central coach station at Heathrow to Victoria Coach Station. Do I really need to buy my coach tickets ahead of time, or do you think I can just wait and buy them once I get there? Our plane lands at Terminal 4 at 10:30am on a Friday. Thanks in advance for your help!
