Hilton HHonors - Help for Budapest West End Hilton Reservation

I booked a reservation in this hotel using the January sale (prebooked) for three nights in July for about $440. Unfortunately my wife broke her foot and we cannot travel. I contacted the diamond desk to see if anything can be done - either a cancellation for medical reasons, a postponment to another time or if they even just giving me stay credit if they would not waive the fee. The diamond desk claimed they contacted the hotel (after several weeks of trying to get an answer from them - they were not very useful in this situation) but they claimed the hotel would not respond to them. I e mailed the hotel directly using the e mail address the diamond desk gave me but I didn't even get a response from the hotel.
Do any of you have suggestions/contact information that I can use?

Usually travel insurance would cover loss of pre-booked accommodation due to medical reasons...?

The hotel is not obliged to, but of course anything positive would be seen as a customer service gesture... Have you tried calling the hotel, speaking to the sales manager and pleading your case?

Call the hotel. I have stayed here 3 times in the past few years and they treat elites very well, even a lowly gold like myself :D

See if you can get the name of the GM by calling the Diamond Desk or the hotel. Then send a fax with your request.
