A Classic Swap is a trip where members swap their homes directly. You go to theirs, and they come to yours.
Classic Swaps can be conducted at the same time, or they can happen non-simultaneously, at different times of the year. The details of when these trips will take place are set in the trip discussion before the swap is agreed by both members.
There is no charge for Classic Swaps (other than your annual membership fee) and you can arrange as many trips as you want.
