Do you disclose a freebie?

Here's an interesting post from a blogger who writes for travel sites, discussing how one might approach writing about a travel experience that was provided on a promotional basis. She suggests some guidelines to use while writing about a travel junket, but the most important point she makes is that you need to be honest with your readers. If you got a free night in a hotel, especially if the hotel staff knew you were a travel writer, that might make your experience different from a paying guest's. Thinking about how to communicate ethically is important for any writer.
