By coincidence, I had just done a check on my site with javascript disabled,because I had heard lots of people disable this function in explorer. I wanted to see what effect it had on my site. The only thing that was missing were the google adssense ads!I did a test on your site and you have exactly the same occuring. Seems like some of the posters on this thread may have it disabled too as some could not see your ads.
No sure if this just relevant to php though?
check mine out at:

You should see tha adsense ads down side of hotel listings if you have it enabled or blank down the side if it's disabled.
To check if you have it disabled or to re-enable it go to IE tools-internet options-security-custom level-scroll down to scripting.
Be very interesting to see what percentage of pcs do have it disabled, and what is the main reason for it,is it to stop pop ups or something? Might be a good idea to have a poll to see what percentage of people have it disabled?
