In the threads about taking the train to Sintra, I cannot find any references to luggage. We will not be doing a day trip, but rather going to Sintra to stay for a couple of nights, and then on to Porto. Thus, we will have suitcases. Is it possible or advisable to take large luggage on the trains to Sintra? From what I read here it is basically a commuter train, and I know that I certainly do not like taking suitcases on the commuter train where I live(Tokyo), although I do do it if I can get my flights at the right time, meaning leaving on a Sunday and coming back on a Saturday or Sunday when their is no rush hour.
Should we just take a taxi? And what about the train going up to Porto? Is that train suitable for taking large suitcases?
