The hotel was unable to accommodate a change of date or refund due to the Heathrow shutdown. However, they were more than happy to double the prices of rooms on the same night to take advantage of the situation. Good practice, guys! Further response to GM after correspondence: David, your comments are patronising at best. I am very aware of how dynamic pricing works, and with a cancellation, there should be more available rooms, and pricing should fall. While I understand the practice of not being able to cancel rooms without due cause leaves the hotel out of pocket, this is an extraordinary circumstance, and just saying that we should have gotten insurance is merely washing your hands of it. Would have been happy to stay in the summer for potentially a longer time, and the hotel could have provided stay credit. But the hotel has decided that there is no room for exceptions. You have my email, should you wish to contact me. The booking was for 21st March.
