What is the best way to pack everything I need for a week long trip in a backpack?

First off, I'm not sure what the best type of backpack for me is. I'm 5'2 so I have a smaller torso.<br><br>I'm flying on a plane for the first time so it will be a carry on. I think carry on backpacks are 21-22 inches tall. Will I need to carry it vertically or horizontally?<br><br>I'm taking a bus after the flight to a hotel where I'll be staying.<br><br>I'll be in a warm climate for 7 days. Here's a quick list of what I'll be bringing.<br>- 2 pairs of shorts<br>- 2 pairs of pants<br>- 6 shirts<br>- 1 rain jacket<br>- 1 sweater<br>- 1 long sleeve shirt<br>- 1 light jacket<br>- 1 pair of hiking boots<br>- 2 pairs of sandals<br>- 2 pairs of socks<br>- 2 bras<br>- 2 pairs of underwear<br>- Underwear for the week and a few extras<br>- Toiletries<br><br>What is the best way to pack all this?<br><br>I'm also going to be bringing a water bottle. Would it be better to bring an empty water bottle in my carry on and fill it up at a water fountain after I go through security?<br><br>Is there anything I should bring that I haven't listed?
