NonRefundable Gatwick Hotel

[Tone Arranger]

Hi,
Like many others, I booked rooms at Gatwick Airport, Hampton by Hilton, ahead of our flight to Orlando in September.
I booked one room with Holiday Extras and 2 rooms with Hotels.com.
I chose non-refundable, what could go wrong ?

We have now decided to abandon this trip and try again for Sept 2021, but of course these are non-refundable rooms. I guess that's end of story, nothing to be done ?

But it seems to me that there's no point cancelling in advance, if I cannot get any refund, as maybe the hotel would still be closed at that time and would have to refund then ? Not wishing bad for anyone who may still be hoping to get away then.

Or are the rooms 'marketable', if say other Dibbers manage to get a trip at that time, could we give the rooms to others and share the cost ? Is that "allowed" or feasible ?

Alternative is to let it run down, it won't cost any more, and if nothing else have a night out at Gatwick. Too sad ?

Any ideas ? 2021 alternative already looks much more expensive re tickets etc, so any £ I can save from 2020 would be welcome.
