I don't see anything in your code to send it to the server.

In your javascript, you'd want to add:

        var param = $(this).attr("href").replace("#","");
        var concept = $(this).text();
        var options = [param, concept];

        $.ajax({
            type: 'POST',
            data: {userOptions:options},
            url: '/Home/Index',
            dataType: 'json'
        })
        .done(function(data) {
            // handle response
        })
        .error(function (req, status, error) {
            $('#result').html('Error: ' + error);
        });

Then on your sever you could receive the data with:

    [HttpPost]
    public JsonResult Destinations(IEnumerable<string> userOptions)
    {
        // do something with userOptions...
        JsonResult result = new JsonResult();
        result.Data = someData;
        return (result);
    }
