Hi @Anne0.
I‘m not sure if I’m misreading your query, but I used my voucher to pay for accommodation.
Usually travel is arranged before accommodation so you have the correct dates.
If travelling by air, you could organise accommodation in advance, prior to booking flights.
If not going somewhere where it will be high season or always in demand, then if your flight travel is out by a day or two, you can send a request to change accommodation to add the extra dates.
However, depending on your location, there is always a risk that could lead to having a night in “the stables,” so to speak!
Just when you book the accommodation, let the host know you are paying with a voucher ... if there are any complications, or changes in plans.
Airbnb will alter the difference in charges between the voucher and the total cost. It runs smoothly at checkout.
Hope this helps.
🙂
