Some sound advice to peeps travelling to London for the 1st time

#2024mapped After two trips to London (making all kinda mistakes), here are my few pieces of advice: 1) Transportation - Paying with a contactless card, it’s automatically capped at £8.5/day (which already covered the journey to 99% of the attractions in London) - Night tubes (5 lines) runs whole night on Fri/Sat so people who wanna experience London nightlife without breaking the bank to call Uber can stay close to the related stations. 2) Attraction - for London skyline viewing, there are many free observatory than the Shard (which is crazily expensive, eg. Horizon 22 > Sky Garden > the Garden at 120 / the Post Building > level 10 at Tate Modern - for markets hopping, Borough market has very great cheeses (pay attention to a booth selling 15-month Comte and another selling all sorta liquor-infused cheeses); Leadenhall market has very cool, classical-influenced architecture; Portobello road market is long but rather boring to me, however. - for museum: many great museums in UK are free-entry (much loves), which could be a blissful nuisance because there would be too many to go; prioritize Victoria and Albert Museums and, of course, the British Museum. - to cover most of the London trademarks in the most efficient manner, a stroll along Thames River (in a day or two) would be a good idea to consider—but I’d suggest do it from east to west, coz many building doesn’t look that good against the sunlight. *feel free to ask any questions in the comments*
