Hi Londoners! Help save me from boredom!

Go here: London transport Museum

I thought this place was great and you can do it in a day. A lot of places need 2, even 3 days to tour properly. Covent Garden is nice too, an expense but be aware that you are in tourist capital city. The food in regular places isn't the best, dirty behind the scenes. Here you a a fair but not long walk away from the London Icon Big Ben (actually Elizabeth tower). Smash the tube over to Tower hill, cross the bridge, an engineering marvel, and if you have pots of money, (book ) have a meat feast in Goucho's:  Goucho's . It's not cheap but is the nuts if you go there on a good evening and are lucky with a decent window seat. After, you can stroll up the South bank next to the Thames, see many types of 'artists' at work, a skate park and that big wheel thing and then raid some bars for some extremely overpriced Italian lager.

It's gonna cost a fair few quid but you get to see many things. My advice for visiting London is to structure your day before hand, the tube is great and staff are brilliant most of the time, get an Oyster card for public transport, you can then just beep your way around London on the tube and busses. Avoid UBER, no one likes them but don't be phased if a black cab won't stop for you, they are out looking for better fares.
You will waste a long time getting lost and disoriented if you don't plan so know where you are going, what you are doing and keep valuables in your front pockets where you can feel them. It's a great place but it is packed with all walks of life.

Sounds like my perfect day. 

I lived and worked in Holborn for 2 years.

I've lived in London for 25 years and there's really not that much car-related unless there are specific shows on, something good happening at the Ace, or the Chelsea cruise, and I don't know of anything happening in town that day. Many of the museums are free to enter though - the Science Museum usually has enough car or engineering related stuff to satisfy a petrolhead.

BUT if you take a trip down to Brighton on the 2nd it's the awesome, historic Brighton Speed Trials. A vast array of interesting stuff always turns out for this - it's been running since 1905

You can watch the cars run for free by just finding a spot on the prom, but I like to mosey round the pits so usually get a ticket.

When in London, may I recommend a trip to Euston or Kings Cross from where you may go to Manchester or Newcastle? 😁

This place would be a great visit if you are staying anywhere near Heathrow?

Some good stuff when visited last. Perhaps not so good if you aren't near Heathrow though.....

Wow! Thanjs for all the replies! I haven't yet booked my sleeps for the night but will be aiming for as cheap as possible as I would rather spend the money in California! I now think my day will be spent in an array of free museums or in Brighton! Is Ace cafe fairly easy to reach from the city centre?
