We understand how exciting planning a trip can be, as well as how frustrating it can be if you don't hear back from a host right away. On average, hosts reply to messages within a few hours. Keep in mind that you may be in different time zones or the host may not have Internet access at the moment.
Generally, we recommend messaging a host by clicking Contact Host before submitting your reservation request. This allows you to ask about availability and anything else you might want to know. Then you can book with confidence, knowing that the host has availability and will accept your request. Once a host has confirmed their availability, you can go ahead and submit your reservation request.
If a host hasn't responded, consider reaching out to other hosts in the area. You can message as many hosts as you'd like, so it's up to them to respond to you in a timely fashion or risk losing their chance at having you as a guest. Unless you're planning on renting multiple locations for the same dates, make sure you do not submit more than one reservation request at a time, as you may end up booking multiple reservations during the same time period.
If you already submitted a reservation request and want to cancel it, as long as it has not yet been accepted, you can retract the request without penalty.
