In a traditional swap, two families exchange their homes directly. You go to theirs, and they come to yours. They can occur simultaneously or non-simultaneously, at different times of the year. Prior to the swap being agreed upon by both members, the details of these trips will be discussed. Besides your annual membership fee, swaps are free, and you can arrange as many trips as you like.
You have a gorgeous home! Might Budapest in autumn be of interest to you?
Budapest is definitely on my bucket list. If you're interested in a traditional swap, I'd love to talk to you about it.
