Tickets booked lastSeptember

[snookhams]

I booked my tickets on the internet last september for my visit this coming August (I do like to be organised), do I need to take anything other than the confirmation that I printed out from the e-mail that was sent - for example do we need photo ID, and how do I go about visiting SW before I go the DC

I was told to bring I.D. and the confirmation letter.
