Bravo!
Few thoughts:
Down load the ETA App. Fill it out. This is a new requirement for traveling to London
Premier Inn chain is perfectly fine. Definitely peruse the website.
Even for a lengthy trip I travel with a carry on. It can be done. Have done on all my London visits. Matter of impatience. Don’t want to wait for my luggage.
Once I’m through immigration I’m either taking the Elizabeth Line or the Heathrow Express ( if HEX ticket should be purchased 3 months out)
Make list of “ must “ sees. Review Google maps to see travel proximity between places. Know most places open at 9am or 10am. Plan accordingly.
I’m old school and use an Oyster Card to use on busses and the tube and for some trains ( used it for the train to Hampton Court)
Understand that besides having liquor pubs are meeting places for families so don’t be surprised if grandma is in the pub with a grand baby in a pram. Same goes for pub dogs and cats. Personally I’m fine with pub grub.
This past trip ( 6 weeks ) discovered the General at the Seven Stars pub which is near the Royal Courts of Justice. Google The Seven Stars pub and you’ll see a picture of the General.
Make sure your Credit Cards are tap ones. I prefer using an Oyster Card only because getting a CC out of a wallet in the hustle and bustle of the Underground is untimely. Oyster can go in a pocket.
Also if I lost a CC I’d be very upset. Loosing an Oyster would be loosing £ 7 …i could live with that. Annoying but not agonizing loosing a Credit Card.
Look at an underground map. Note that the tube lines are designated by color . Look at Timeout London website. In the description of events, sites to see , etc Timeout directions will mention tube line(s) in the directions.
Little bit of translation helps:
Ask for loo or toilet not rest or wash room.
Crisps are potato chips
Sweaters are jumpers
Jeans are perfectly fine to wear
Not all hospitals have ERs.
Most Museums are free ( I always leave a donation)
Lots of wonderful ethnic cafes and restaurants : Malaysian, Indian, Indian, French, Spanish to name a few. Have noticed within the past 6-7 years hamburger and pizza restaurants have gained popularity. Same with coffee. Besides the evil
Starbucks empire, you’ll find Costa Coffee, Caffe Nero Research and Redemption Roasters. Can also find coffee at some Pret a Managers. Learn what is an Americano or a Flat White. Asking for a black coffee still generates a questioning look.
See Theatre. Nothing better than theatre. Check both Whats on Stage and London Theatre websites.
Over the years been privileged to see Judi Dench, Mark Ryland, Brenda Blythen and Maggie Smith.
If a walker the Thames River path can be followed for miles. Same with the Regent Canal patheay.
The Queens Garden in Regents Park should be in bloom ….same with the Isabella Plantation in Richmond Park.
London is a great city.
Train travel most enjoyable.
Really great parks to explore. Pretty sure Ian will offer intel about the Lake District.
Lastly, I think the best view of London is from the Royal Observatory.
I always recommend 63 Bayswater as a place to stay for first time visitors. 15 minute walk from Paddington Station. Across the road from the Lancaster Gate Entrance into Hyde Park/KensingtonGardens. Lancaster Gate Underground Station 1/2 block away. Charming Mitre pub block away.
You’ll have a great first solo sojourn.
EDIT: for architecture: travel to Blackfriars station and have a meal at the gorgeous Blackfriar Art Deco pub which is across the road. OR visit The Gherkin ( St Marys Axe ) then the adjacent Ledenhall Market OR head to Canary Wharf or visit Kyoto Gardens and then the Design Museum or Holland House in Holland Park
