I am currently a member and have been one for 4 years with 1 more year on my current 3 year membership.
Although I didn't use it this year hopefully I will next year.
The prettiest place we ever spent the night and we spent 3 nights there was on a farm in Wolfville, Nova Scotia that overlooked the Bay of Fundy.
We have used Harvest Host's approximately 10 times. We have always purchased something from the host.
I have used Harvest Host's in 3 States and 3 Canadian Providences.
If I had been aware of it when I made my trip to the West Coast 5 years ago I would have stayed at a lot more places.
