Deserialize XML into objects c#

I have the following XML which I need to deserialize.

<?xml version="1.0" encoding="UTF-8" ?>
<event code="2wuj0ticofhzt" self="/events/2wuj0ticofhzt" revision="1260234836">
<name>Test Event 2013</name>
<partner-settings>
<partner-setting>
  <registration-type code="1yfopbwhk" link="/registration-types/1yfopbwhk" />
  <personnel code="3eclag1dsrjfi">
    <free-badges>unlimited</free-badges>
  </personnel>
  <personnel code="0nxgc6mfec8yh">
    <free-badges>3</free-badges>
  </personnel>
</partner-setting>
<partner-setting>
  <registration-type code="1ygg67prw" link="/registration-types/1ygg67prw" />
</partner-setting>
</partner-settings>
</event>

Here are my classes that I have created (I only need to deserialize the fields I have in my classes)

 [XmlRoot("event")]
 public class Event
 {
    [XmlAttribute("code")]
    public string Code { get; set; }

    [XmlAttribute("name")]
    public string EventName { get; set; }

    [XmlArray("partner-settings")]
    public List<PartnerSetting> PartnerSettings { get; set; }
 }

[XmlType("partner-setting")]
public class PartnerSetting
{
    [XmlElement("registration-type")]
    public RegistrationType RegistrationType { get; set; }

    [XmlArray("personnel")]
    public List<Personnel> Personnel { get; set; }
}

[XmlRoot("registration-type")]
public class RegistrationType
{
    [XmlAttribute("code")]
    public string Code { get; set; }

    [XmlAttribute("name")]
    public string RegistrationTypeName { get; set; }

    [XmlElement("type")]
    public string Type { get; set; }
}

[XmlType("personnel")]
public class Personnel
{
    [XmlAttribute("code")]
    public string Code { get; set; }

    [XmlElement("free-badges")]
    public int FreeBadges { get; set; }
}

When I currently deserialize the above XML it all works except from the Personnel object where I get 0 returned when I'm expecting to see 2.

I'm not doing anything differently when I'm trying to return a personnel list (i.e. XMLArray attribute, return a List) to a partner setting list but for some reason it won't deserialize.

If anybody has any suggestions it would be much appreciated
