Ah well - don't ask, you don't get. I'm certainly not complaining about life in SF. The only ones who do are from Southern California, since they think it's too cold.
Interesting about the discount idea. As a parallel, when I buy a new gadget like a TV or camera, I review it on my blog. When others Google to research the product, my impressions frequently pop up. I'm therefore influencing in some small way their reputation and the perceptions of their prospects. The same will be true of travel, so to do your best to make those impressions favorable would seem an excellent idea.
I can't see any reason why you wouldn't include bloggers in the 'press trips' if you know they are influential. Communiations is all about reaching your target audience. Whether they read the print press, online media or blogs, doesn't matter per se. Many blogs have higher readerships than monthly publications or local press, so should certainly be included in the comms plan. Heck, The White House even included a blogger in its briefing recently.
Any free trips for tech PR bloggers going, will be gratefully recieved (ahem).
