If you do not want to drag a large suitcase through crowded stations, stairs, transfers, or long walks to your hotel, luggage forwarding is worth understanding. It helps most when your energy is low and your surroundings are new.
When it feels most valuable
It is especially helpful when you land after a long flight, plan to change hotels, or know that your first day includes busy urban stations. It is less about luxury than about preserving mental energy for the parts of the trip you actually care about.
