We are planning to visit Windsor Castle on Tuesday June 5th. We want to take a train to get there before the busses to avoid the crowds. We are planning 3 hours to tour the castle and then have lunch in town and get back to London. My question is if anyone has any tips regarding the visit. I am going to try to purchase tickets online either before we leave the US or when we get there. Do you think this date will be busy? Can anyone provide train information to Windsor? Many thanks for any advice.
