Two weeks out is the sweet spot. Close enough that you know the weather forecast. Far enough that you can still order something from Amazon. Run through this list, in order, and the day-before feels like packing a weekender instead of a panic.

FAQ
Is travel insurance really worth it?
For trips over $1500, almost always. For shorter cheaper trips, a "trip delay + medical" policy ($30–60) is still worth it.
What about TSA PreCheck / Global Entry?
If you fly 3+ times a year, apply NOW (wait times can be 3–6 months). Global Entry includes PreCheck.
Should I exchange cash before going?
Small amount for the airport/first day, yes. Large amounts, no — ATM exchange rates at destination are better.
