I am plan to visit Buckingham Palace on end of this month, should I pre-order it online now or I can wait until I actually get there? I will be traveling with a baby, so I really don't want to spend too much time on waiting in line...
Is the line always pretty long?
If I order it online now, do they ship the tickets directly to me now (I live in US) or I need to collect the ticket when I get there?
Do they provide a special entrance line for those who already pre-order their tickets?
