I thought I read that if you purchase a ticket on the Aero Bus (3.50 Euro, or a little less if purchased online), you can use the ticket on trams and buses in Lisbon for 24 hours in addition to riding the Aero Bus. Is this true?
For the 24 hour pass, how to purchase one that covers buses, trams, elevadores, and Metro? I think I need to buy a viagem card first and then load the pass onto it, but is that the regular 6 euro pass, or does that one exclude the Metro system? I know Metro and Carris are run by different operators. Are there 2 different viagem cards - one for use with Metro along with Carris, and one without?
Where in Belem does the CP train stop? Is it anywhere near the waterfront, or is the tram about the only way to get to the Torre de Belem and Discoveries Monument? Does the 24 hour pass cover use of the train within Lisbon (for example, to get to Orient)?
