Treat phone battery as part of travel planning on a long day.
Digital tickets, train times, directions and group messages can all compete for the same battery. Start charged and decide whether your normal phone lasts comfortably through the itinerary.
A power bank is useful when you repeatedly need it, not because every meet-up needs another gadget in the bag.
Pack for the gaps between planned stops.
If the day includes cafes, meals or easy access to shops, you may need less food and drink than an outdoor route with no services. The event itinerary tells you more than a generic day-trip checklist.
A light extra layer can still be useful when a day moves between transport, indoor venues and time outside.
Make the bag easy to carry for hours.
A huge backpack is not useful if it makes every queue, train seat and social stop awkward. Take the smallest comfortable bag that holds the real essentials for the day.
Keep valuables and anything you need frequently easy to reach without making the bag easy for somebody else to access in a busy place.
