Buy your ticket in advance—online or via apps like Trainline or Thameslink. On-the-day prices can be silly, especially during peak times. A cheap advance single from London to Luton can be as low as £10–15. Compare that to a taxi (hello, £60+), and you’ll feel like a budgeting genius.
Trains run from about 5 AM to midnight. But check for engineering works on weekends: track maintenance can turn your smooth ride into a replacement bus shuffle. It’s rare, but it happens—like a surprise plot twist.
Oh, and the DART is wheelchair-accessible and baby-stroller-friendly. No need to fold your life into a suitcase.
