The Royal Parks have produced an interactive map to help visitors to London make the most of being on the streets on Royal Wedding day.
Aside from the fact it rains red, white and blue confetti across your screen it's pretty helpful for those unfamiliar with that patch of central London. Not only is the all important procession route clear, landmarks are labelled and the map includes the location of public toilets, refreshment points and - naturally - official merchandise stands in St James's Park and Green Park.
For those who've decided against lining the mall there's still mass flag waving and cheering action to be had in Hyde Park and Trafalgar Square where the wedding will be beamed live to big screens.
Should you not wish to wear your wedding watching in public, there's a comprehensive round up of TV and radio coverage courtesy of The Daily Telegraph.
