When I had Jury Duty, a similar thing happened. I told them I could serve up until a specific date because I had a non-refundable commitment and they excused me. I definately didn't want to loose any money. If this is not an option, I too, would do as Donna suggests and call the hotel. You might have to fax them some proof. I think Priceline now offers cancellation/insurance for $5. Did you happen to click that box? Good Luck.

I hadn't known I could tell the judge I had non-fundable airlines tickets...and was selected for the jury. I told the judge at the conclusion of the trial (he met w/the jury members)....he said, "Why didn't you speak up? You wouldn't have had to serve on this jury had you told me you had planned a vacation - especially, with non-refundable tickets."
Tell the judge you're situation - you'll likely not be selected and will be released.
When I showed up this morning I finally managed to give the Bailiff the doctor's note explaining what I had and why I shouldn't be on a jury right now. When the judge and the four attorneys heard that I was contagious, their permission for release was gladly given!
So, our hotel dates are safe. Thanks again for your help.
