I am considering taking the Lusitania train from Madrid to Lisbon which is an overnight train, leaving Madrid about 11PM and getting into Lisbon around 8AM. Has anyone taken this train before? There will be two of us and we will get a cabin - not sure which one to get though the 'gran clase' is quite a bit more than the 'preferente' - the difference that I see is the private toilet and shower. Did you book it in advance or wait until you got to Spain? (I will be in Spain about 10 days before the train trip). Any advice would be helpful. Thanks!
