No need to ever cancel a booked hotel room due to last-minute changes. Instead, sell it to another person at the same cost or better than the refund price.
We all know that we cannot get a refund at last-minute hotel room cancellations. There are a few things that bother me about this. First is that the room booked by me, if cancelled at the last minute, will most definitely be "resold" giving an opportunity to the hotel to take double rent. Sometimes, travel agents pocket the price with the same reason. ..last-minute cancellation.
How about creating a portal, site or app that the travellers can log on to and list their destinations, cancelled hotels, check in & check out details, number of rooms and the price they intend to release the rooms for. I know not everyone cancels their hotel room but there surely are many instances everywhere around the world every day due to delayed flights, travel plan changes and many other unavoidable circumstances.
The community can grow as we have seen with every innovative way of travelling. This particular idea can help solve many last minute jitters, cancellation, refunds, travel pressures, etc. If it grows it can be applied to just about any aspect of travel.. including flight tickets.
