Keep movement honest
The best transport plan is Speicherstadt and HafenCity first, Elbphilharmonie or Miniatur Wunderland in the same block, St Pauli later.
- Anchor the day around Speicherstadt or Elbphilharmonie.
- Keep St Pauli for the right weather and timing.
Getting around Hamburg becomes easier when you stop treating every stop as equally close. I would choose the base first, group the nearest anchors, and leave the wider move for a clean second block.
The practical rule is simple: Speicherstadt and HafenCity first, Elbphilharmonie or Miniatur Wunderland in the same block, St Pauli later. That keeps the day grounded instead of making it feel like a decorative list.
