You get null because you're sending the json array in wrong way.

First, you should serialize your json array:

$.ajax({
        // Whatever ...
        type: "POST",
        url: "yourUrl",
        data: JSON.stringify(guests),
        // Whatever ...
    });

Second, your controller should get a string:

[HttpPost]
public ActionResult ActionName(string guests)
{
    // ...
}

and finally, you should deserialize that string to the related type:

[HttpPost]
public ActionResult ActionName(string guests)
{
    // this line eserializes guests ...

    IList gs = 
       new JavaScriptSerializer().Deserialize>(guests);

    // ... Do whatever with gs ...

    return View();
}
