The Setup
Iceland in shoulder season is a good stress test for any packing advice, human or artificial: the weather changes four times before lunch, "cold" can mean anything from a light frost to sideways sleet, and half the country's best experiences (hot springs, glacier hikes, waterfall chasing) need completely different gear. So we typed one simple prompt into an AI assistant — "what should I pack for a week in Iceland" — and checked the answer against what actually works on the ground.
What It Got Right
The basics were solid: layers over one heavy coat, a waterproof outer shell, wool socks, and a reusable water bottle (Icelandic tap water is some of the cleanest on earth, so bottled water is a waste of suitcase space). It also correctly flagged a headlamp for winter visits, when daylight can run out before 4pm.
Where It Missed
Three gaps showed up quickly. First, it recommended a "warm winter coat" without mentioning wind — in Iceland, wind chill does more damage than raw temperature, and a coat that isn't windproof is close to useless on the south coast. Second, it forgot swimwear entirely, which matters more in Iceland than almost anywhere else on earth thanks to geothermal pools and hot springs in every town. Third, it suggested a generic "travel adapter" without noting Iceland uses the standard European two-pin plug (Type C/F) — useful specificity that saves a last-minute airport purchase.
