I’ve hosted many and been a guest at many. Here’s my WS strategy that works very well. I will contact 2-4 hosts in a town where I’m hoping to be hosted 3-7 days in advance. I’ll email/text saying, “I’m touring through your area and think I’ll be near you on this or that day. I’m wondering if you might be able to host?” If I get 3 positive replies in the same town, then I’ll pick one and then tell the other 2 thanks, but I’m covered. Then, when you are a day or 2 away you can confirm your exact arrival day. More often I’d only hear back from 1 or 2. By writing further in advance it gives folks longer to reply to you. I’ve found a number of folks only list an email address as a contact that they rarely check. It also gives you more time to find alternatives. And it gives hosts more time to check YOU out.
As a host, I always look up WS guests and read reviews given about them. Besides not giving enough notice (48 hours is less than what I’ve seen a lot of hosts prefer) the original poster may not have heard back from some hosts because he had not built up much reputation on his account. Especially if he was a man riding alone. One of the things that makes WS possible is that hosts and guests can look up the accounts of others and see what has been shared. If I get a request from a rider that has few or no write-ups, I’m likely not to reply back. The whole WS system is based on trust and a host has to trust that some stranger isn’t going to come into your house and cause mayhem, just as a guest wants to feel safe in someone’s home.
This is partly why I believe anyone that wants to go enjoy the (free) hospitality of others darn well oughta sign up as a host as well. Not only is it great payback for when you are a guest, but it also helps build your account reputation.
My last suggestion is to be a gracious guest and pick up a jar of jam, or bottle of wine, or basket of berries from a roadside stand on your way to your host. Sure it’s a couple of bucks, but the food, drinks, hospitality I’ve received at 95% of the hosts I’ve been to have far exceeded the small gift.
For me, the aspect that I most enjoy about WS is entering the house of strangers and then leaving the home of friends. Yes, it’s fun to meet and enjoy the company of fellow tourists in a campground, but you often learn so much more about a town/city/region through the eyes of someone that lives there and that you break bread with.
