I would love to create a travel website, but I would love to know what WordPress plugin I can use to allow visitors to submit their story on my blog. I want it to be interactive, so they can write their experience if they choose to.
Try this: http://wordpress.org/extend/plugins/quick-post-widget/
Though I can't confirm it works with latest wordpress nor have any personal experience with it.
You could code one yourself with a simple HTML form, but you need to learn the wordpress funciton to insert posts into the database in PHP.
