The first thing we noticed was the stunningly large TV presence - I was expecting cameras but for some reason the scale of it all amazed me.
I did feel like a bad mother when my little ones told us we'd never taken them to see the Palace before - we've done museums galore but not "the sights". Time to set that right with a look at the balcony - and an explanation that the next time they see it on TV there will be lots of people in big hats standing on it.
We had a quick whizz round the Royal Mews to look at the horses and carriages and take bets as to which coach will be used - I'm pretty sure it won't be one of these:
or this one (though the girls think it should be!)
A march down a refreshingly traffic free Mall took us to Horseguards Parade where even our equine companions were suffering from hay fever. (Did I mention the pollen? And the dust? Blimey.)
We tried to show the girls 10 Downing Street - and I'll show my age my revealing that one of my earliest memories is of being taken to stand outside the house itself where I'm sure my parents gave me exactly the same serious description of its importance as we gave our girls. I think they took about as much notice as I did ...
Can you believe we've never even taken them to see Big Ben? What kind of monsters are we?!
And then what was, for me, the highlight - going in to Westminster Abbey which I have not done since I was a teenager taking a German pen pal to see the sights. It is a glorious place - the building itself is stunning but it's filled with so many gems - and we were lucky enough to be shown some extra special highlights by a friendly verger - he allowed the girls to climb through the Queen's own special door to her seat in the choir stalls (complete with embroidered booster cushions) , showed us Dick Whittington and his cat in one of the stained glass windows and even let us under the rope in front of Isaac Newton's memorial to show us the details of the carving you can normally only see from 20 feet away. Be still, my beating geek heart!
Sadly no photography allowed inside, but when we see this shot from these cameras on Friday, we can say - we were there! The girls said it was their "best day ever". It was certainly one to remember.
To those of you who are planning to watch, have a lovely day - we have our wedding feast planned! - and I hope that those of you who have no interest in it can spend the day doing something you enjoy too.
