Ease of public transit travel in Portugal, northern Spain and Southern France
 

Hello
we are planning a trip starting in Lisbon then on to San Sebastian and ending in Bordeaux. A rental car is between $2600 and $3200 due to the one way plan.

Trains and busses are available for a fraction of that. I'm wondering how easy it is to move along our route and if 2 rollaboards are allowed?

We've taken trains in Germany and Italy sporadically but never for an entire trip.
trip.

Advice and experience appreciated!
