Hi, I am a host and have a travel coupon to use up. Just went to book something and it said 'reserve' , does it give me somewhere later down the line to add my travel coupon or does 'reserve' mean that the host can just accept you as an instant book. I don't want to 'reserve' and loose my travel coupon that runs out in a couple of days. Any ideas? can't find anything in the help files about this. Thanks Bez
