It’s okay to pack ten…

It's okay to pack ten outfits for five days if you're too tired to think straight when packing, right? I am feeling ridiculously girly doing this, but it's seeming easier to just throw more clothes into the suitcase than make decisions (mostly about how warm / cold I think I'm going to be in the convention hotel, and whether I will want to wear skirts or jeans as a result). It'll all still fit in a carry-on, which is the important thing, right?
