I'm in the same boat (whilst maintaining social distancing...!
) with my trip to Israel in May & June. I usually opt for free cancellation but booked some pre-paid or non-refundable nights as the rate was significantly cheaper. I've cancelled all the 'without penalty' places & will now wait & see. Once I know various travel bans are in effect for my travel dates, then I will tackle the reservations with restrictions.
We all understand the financial ramifications for ourselves & the accom providers; I'm hoping some middle ground can be reached. Initially I will contact the accom directly through booking.com messaging followed by asking b.com to act on my behalf. I've always found their Customer Service to be absolutely top-notch. I'm expecting (& have accepted) the money paid or yet to be paid won't be refunded/excused so anything recouped will be a bonus.
For clarity, I've booked hotels who appear to have high occupancy rates from the domestic Israeli market....I personally would not ask for a refund from small independents whose family income relies on hosting travellers.
Best wishes to us all as we navigate uncharted territory!
