I am planning to travel to Spain in the fall and wanted to know: how far in advance will I need to reserve a night train? I want to travel from Granada to Barcelona on the night train (trenhotel). Can I make the reservation while I'm already in Spain (a week or two before the Granada to Barcelona trip) or should I make it before I leave the US? Also, if anyone has experience with this, how are the night trains? Is there a particular type of bed I should book to make for a more pleasant (or less unpleasant) experience?
Thanks,
Liz
