Now I know you did not ask this question, but you may, may want to check out a free app called Tripit. It will store off line your hotel, airlines, travel documents ( don't know about spreadsheets) but WILL store web links, and maybe word docs,) addresses, photos, notes, will also ( on line) show where there are restaurants and sites nearby where you are staying. It is a great place to store trip information and have it always on your iPhone.
It is a great free travel app and a great way to organizing your travel infor and you can take a photo right then and there and send it right to tripit. Or take a photo and then later on send it to Tripit. You have to see it to understand totally what I am writing you about.
If you don't like it, delete from your phone.
Hope this helps.
