If you have access to a Mac, you can consider what I did with an application called DeepVacuum.
A relative took a cross-country bike trip and posted his daily updates online with pictures. Once the trip was over, I was able to download his 45 day diary with this software. It saved the content as a PDF which you can copy from your computer to a Kindle.
I have not read his diary on a Kindle but I printed out the hard copy. It rendered nicely on 8.5 X 11 paper which he keeps in case the website ever decides to take down his diary.
Hope that helps.
