There are lots of ways to get into London proper, including the Piccadilly line of the Underground, and since money isn't currently a concern for us (in person, the one-way fare is a pricey £22 fare, or about $26), we'll take the Heathrow Express.

It's a purple-liveried, direct connection to London Paddington in just 15 minutes.

We could walk from here to our first stop, since our virtual weather is perfect, but instead we'll walk to the rear of the station and head for the Circle/Hammersmith & City Underground station.

You could catch the Eurostar to Paris or Brussels here, but we'll save that for another time.

Take your time, and have a look around.

Have a look around the British Museum on Google Street View.

When you're done, we'll exit through the gift shop and head back outside.

We're in between a few Underground stations here, so picking one we'll head southwest to Tottenham Court Road, We slap down our Oyster cards at the turnstile on our way down to the Central line, heading east to Bank.

We head up, unaffected by fatigue or heights, and look back down onto the elaborate tile work so far below.

The Tower of London The food on your first-class flight was good, but you're starting to get hungry.

The Tower's full name is a much better description of what we're looking at: Her Majesty's Royal Palace and Fortress of the Tower of London.

After exploring the castle and ogling the Crown Jewels, we head south, across Tower Bridge (which isn't, as many incorrectly call it, London Bridge).

We have time for a quick trip to the top of the Shard, the tallest building in the UK.

Paul's again, but this time we're on the far side of the river.

Rising above us is the imposing brick tower of the Tate Modern, looking more like a late Victorian era power plant than a modern art museum (which, of course, it was).

Ahead, on our side of the river, is the London Eye, a Ferris wheel that for a time was the tallest in the world.

Around the other side we'll take a a quick walk through Westminster Abbey.

Across Trafalgar Square, waving at Lord Nelson high on his pillar, time slows for us again as we look around the National Gallery.

The weird and wild cars of the London Motor Museum

After definitely not playing a few notes on the actual piano used in A Day in the Life and Ob-la-di, Ob-la-da (just kidding, we totally did), we head back outside as the sun is setting
