Time outside
Pack for a day at an outdoor event
Venue rules differ, and a bag packed for the wrong ones can cost time at the gate. Give the assistant the official prohibited-items list, the forecast, how long you will be there and any personal needs.
What to check in the answer
The venue's own prohibited-items list is the only reliable guide to what gets through the gate, and it can change after tickets go on sale. Read the current version on the morning you leave. Because hard-sided coolers are banned, ask the venue whether a soft insulated pouch for medication is allowed. How long your medication stays effective without refrigeration is a question for your prescriber or pharmacist, not for a packing list. If the draft includes anything the official list bans, point it out before you pack.
Your next step
Read the prohibited-items page once more on Friday evening in case of late updates. If your medication needs special handling, contact the venue's accessibility or medical team beforehand to ask what on-site arrangements exist.
