Alpha-Pendular Train To Lisbon and Porto. Book Early (www.cp.pt)

If you're flying into Lisbon rather than Faro enroute to Casa Jovic, or if you fancy a trip to Lisbon or Porto during your stay, one of the best ways to travel is the Alpha Pendular train. It's a fast (tilting) train that takes just two hours thirty minutes to make the trip from Lisbon to Tunes - the stop closest stop to Casa Jovic.  Using Tunes does restricts the number of trains available to you, but it means that taxi costs are less, or it's a simple drive. 
Assuming the train schedules stay the same it means you can get the train from Lisbon at 8.24am or 6.24pm. If heading North you need the 7.30am from Tunes, or 3.35pm if you prefer to go later. It means that you could be in Lisbon by 10.04am, in time for brunch, making a day trip feasible. That said, Lisbon is so nice you might want to stay over and come back the following day.
