i think the tickets are allocated by ballot, so its completely random. but you need to apply now. check this page out -- royal.gov.uk/RoyalEventsandCeremonies/T ... olour.aspx
there's not many seats in horse guards though, when you consider how many people end up standing in the mall. the odds of winning a ticket are probably pretty small.
when i went last year it was absolutely packed. i was standing in the mall, and it was about ten people deep all the way down (read my blog
). i think i got there about two hours before it started, or something like that, and if you want a place up against the barriers (because you wont be able to see anything otherwise) then i would say you have to get there at least an hour/hour and a half before. and theres no seats either, its all standing. but there is good banter in the crowd and you'll probably end up talking to to the people around you.
ive got a lousy memory, but the parade probably passes you in about ten minutes, and the royals speed past in about minute. then you've got to stand there for an hour whilst they have their service (which you cant see), and then they come back the opposite way, so you can see them again. and if you want to wait around after that, then you can watch the flypast above your head.
its a long day, with lots of standing, but it was good though. i will probably end up going this year too.
the best places to stand are probably on the corner, where the road bends round from the Mall to Horse guards. if you can get on that bend, then you can watch them come all the way down the mall and into Horse guards. the other good place is on the corner near St. James Palace, where the traffic lights are. because you have a bit more room in front of you there, because of the empty road.
dont go near the palace though. lots of people do that, but i think that is the worse place, because your a lot of your view will probably be blocked by the queen victoria memorial
