1) Always pack a hat. In the winter, a knit hat will keep you warm and take up little room. In the summer, a brimmed hat will keep the sun off your face. In either case, it will save you when your straightening iron doesn’t work in the trapezoidal electrical socket you found in your hotel room.

2) Packing for a trip is infinitely easier when you’ve just done laundry.

3) Don’t pack clothes that require ironing. Hell, don’t buy clothes that require ironing.

4) Never pack something that you haven’t worn before. Otherwise, you’ll find your new shoes too uncomfortable, your new jacket too flimsy, your new underwear too wedgie-prone.

5) Always ask museum staff for tips. They’ll tell you what the best exhibits are, and what you can skip.

6) Never carry your wallet in your back pocket, and never carry your purse on just your shoulder.

7) The second you think of packing something, PACK IT. If you wait, you will forget. And then you’ll end up using a plastic bag as a shower cap. Subsequent attempts to seduce your husband will be impossible after he’s seen you with a Rite-Aid sack on your head.

8) Wherever you are, wherever you are going, bring snacks.

9) Stuffing socks into your shoes can help you save space and ensure your loafers retain their shape.

10) If you can’t afford to lose it (either financially or emotionally), don’t pack it.

11) Wear sunscreen anytime you will be outside, regardless of the temperature or weather.

12) Regardless of size, never bring more than two bags with you– any more than that is unwieldy and difficult to keep track of.

13) Budget hotels almost always offer free wi-fi. Luxury hotels will charge you for it. This is almost always the case.

14) Make photocopies of your passport and leave one with friends and another tucked into your bag. Or, better yet, scan your passport and email a copy to yourself.
