Spring, Summer, Fall, Winter, and Winery. 

Girlfriend getaways practically beg for winery season, which really has no boundaries. It can be a year-round thing if you consider New Zealand, Argentina, Chile, etc.

Top 10 Things To Pack For a Winery Weekend Girlfriend Getaway:

1) Water bottle - wine-tasting dehydrates you.  You'll also need it to rinse, after drinking red wine, so your teeth don't acquire that bluish tint.

2)  Camera - you will want photos of you and your friends.  Particularly if they forget to rinse after the red wine.

3)  Sunblock - bluish teeth and tomato-red skin may sound patriotic, but they really don't look good.

4)  Sunglasses - after the third winery, your eye makeup will be smudged beyond repair.  Just put the sunglasses on.

5)  Any burgundy-colored clothing you own - one of your friends is probably accident-prone.

6)  Tide stick - in case you forgot to bring burgundy-colored clothing. 

7)  Earplugs - another one of your friends probably snores when she's drunk.

8)  Advil - for the next day.

9)  CD full of chick music (Christina Aguilera, Pink, Faith Hill, etc) - when your girlfriends drink wine, they want to sing.  Loudly.
