In short, it depends.
We email and message hosts when Worldpackers have applied to their position, but inevitably some may not respond very quickly.
Here is how it works:
You will only be able to contact a host if they are looking for a volunteer on the dates you are looking to volunteer. If your dates don’t fit, you won’t be able to contact the host.
If your dates match and you send a message to a host without a reply, check their Response Rate and Response Time. This will give you a good idea as to how long you should expect to wait for a reply. And remember if you don’t want to wait forever, simply cancel & close the conversation.
If you have already accepted a host trip confirmation and are about to travel, make sure you write down all contact details (including telephone number, host address, email and even Facebook contact).
