July trade-offs

  • School holidays begin (late July) — crowds at every major attraction increase sharply from that point
  • Hotel rates at annual highs; central London accommodation is aggressively priced
  • The Tower of London, Buckingham Palace, and the British Museum all require advance booking; spontaneous visits fail

May trade-offs

  • Prices climbing toward summer — a week at a 3-star central hotel costs noticeably more than March
  • Chelsea Flower Show week sees south-west London traffic disruption and accommodation pressure
  • Half-term (late May bank holiday) briefly crowding family attractions across the city
