Do-It-Yourself
Guestbook

I searched through a couple different websites and found Mixbook to create our guestbook. I used their "Aqua Themed Guest Book" which allowed you to import pictures next to the spaces where guests will write their name/note. I ended up using an 11"x8.5" hardcover book, and waited until Mixbook was having a sale to order the book. (Full disclosure: those are not our pictures)
Cardbox

I saw a couple of different DIY instructions for Picture frame Cardboxes. I loved the look and decided to make one! I got the frames at Michaels for super cheap, and the fabric for the lid at JoAnn Fabrics. I thought about using our engagement pictures, but I sort of felt like people had seen those too much, so I went with some fun pictures of us from last summer.
Programs

I found this program design on weddingwire, and thought it was super cute. Originally, we were only going to create 1 program and hang it up in front of the ceremony entrance. However, I had a Vistaprint groupon that I needed to fill, so we ended up ordering multiples to hand out to our guests. I edited the template design in Microsoft Publisher, saved the files as jpegs and increased the size 400%, then used Vistaprint's blank announcement and uploaded the pictures. Here and there I used Disney font, to show my love for Disney.
OOT Welcome Bags

I found these large bags at Old Navy for only $1, so I visited my local stores and bought a bunch of them. I'm hoping to fill them with area maps, a welcome letter, some food and water, and maybe a trinket or two!
