I'll make a big travel with some friend this August.
We're planning going from Lisbon to Prague, stay there a few days, then go to Warsaw, stay there a few days and finally come back to Lisbon.
The map planner is recommending me 4 days, but in Google Maps the travel from Lisbon to Prague takes more than one day and the travel from Warsaw to Lisbon is the same.
We are on a budget, that's why I'm still considering adding another day.
Also, can we add another day on the go, if necessary?
