What is the best technique for using ViewModel with mvc C # lists?

I have two templates: event registration package and subscription package, where the template event registration package has a list of subscription packages (see the code below, I removed some fields).

//Model
public class PacoteInscricaoEvento
{
    public PacoteInscricaoEvento()
    {
        PacoteIncricao = new List<PacoteIncricao>();
    }
    public int PacoteInscricaoEventoId { get; set; }
    public short Nrvagas { get; set; }       
    public IList<PacoteIncricao> PacoteIncricao { get; set; }
}

public class PacoteIncricao
{
    public int PacoteIncricaoId { get; set; }
    public string NmpacoteIncricao { get; set; }
}

public class PacoteInscricaoEventoViewModel : ViewModel<PacoteInscricaoEventoViewModel, PacoteInscricaoEvento>
{
    public PacoteInscricaoEventoViewModel()
    {
        PacoteIncricaoViewModel = new List<PacoteIncricaoViewModel>();    
    }

    [Display(Name = "Código")]
    public int PacoteInscricaoEventoId { get; set; }
    [Required]
    [Display(Name = "Nº de Vagas")]
    [Range(1, int.MaxValue)]
    public short Nrvagas { get; set; }
    public List<PacoteIncricaoViewModel> PacoteIncricaoViewModel { get; set; }
    public override PacoteInscricaoEvento CopiarModelo(PacoteInscricaoEvento modelo)
    {
        int indiceElemento = 0;
        modelo.PacoteInscricaoEventoId = this.PacoteInscricaoEventoId;
        modelo.Nrvagas = this.Nrvagas;
        //listas
        //Excluindo os pacotes que foram exluidos na viewmodel no modelo
        if (modelo.PacoteIncricao != null && modelo.PacoteIncricao.Count > 0)
        {
            foreach (PacoteIncricao pacoteIncricaoModelo in modelo.PacoteIncricao)
            {
                //buscando o indice na view model
                indiceElemento = this.PacoteIncricaoViewModel.FindIndex(x => x.PacoteIncricaoId == pacoteIncricaoModelo.PacoteIncricaoId);
                if (indiceElemento == -1)
                    modelo.PacoteIncricao.Remove(pacoteIncricaoModelo);//se nao encontrar exclui
            }
        }
        //adcionando ou alterando os elementos nas view models
        if (this.PacoteIncricaoViewModel != null && this.PacoteIncricaoViewModel.Count > 0)
        {
            foreach (PacoteIncricaoViewModel pacoteInscricaoVM in this.PacoteIncricaoViewModel)
            {
                //buscando o indice no modelo
                indiceElemento = modelo.PacoteIncricao.ToList().FindIndex(x => x.PacoteIncricaoId == pacoteInscricaoVM.PacoteIncricaoId);
                if (indiceElemento == -1) //se nao encontrou altera
                    modelo.PacoteIncricao.Add(pacoteInscricaoVM.CopiarModelo(new PacoteIncricao()));
                else //senao altera o elemento
                    pacoteInscricaoVM.CopiarModelo(modelo.PacoteIncricao[indiceElemento]);
            }
        }
        return modelo;
    }
    public override PacoteInscricaoEventoViewModel CopiarView(PacoteInscricaoEvento modelo)
    {
        this.PacoteInscricaoEventoId = modelo.PacoteInscricaoEventoId;
        this.Nrvagas = modelo.Nrvagas;
        //listas
        foreach (PacoteIncricao pacoteinscricaotmp in modelo.PacoteIncricao)
        {
            this.PacoteIncricaoViewModel.Add(new PacoteIncricaoViewModel().CopiarView(pacoteinscricaotmp));
        }
        return this;
    }
}

public class PacoteIncricaoViewModel : ViewModel<PacoteIncricaoViewModel, PacoteIncricao>
{  
    [Display(Name = "Código")]
    public int PacoteIncricaoId { get; set; }
    [Required]
    [Display(Name = "Nome Pacote")]
    [StringLength(50)]
    public string NmpacoteIncricao { get; set; }             
    public override PacoteIncricao CopiarModelo(PacoteIncricao modelo)
    {
        modelo.PacoteIncricaoId = this.PacoteIncricaoId;
        modelo.NmpacoteIncricao = this.NmpacoteIncricao;
        return modelo;
    }   
    public override PacoteIncricaoViewModel CopiarView(PacoteIncricao modelo)
    {
        this.PacoteIncricaoId = modelo.PacoteIncricaoId;
        this.NmpacoteIncricao = modelo.NmpacoteIncricao;
        return this;
    }
}

So, what is the best technique (or code samples) for creating views models that contain views models in this situation (lists), without using automapper or similar? Thanks
