We will be traveling Stuttgart to Prague on Saturday April 12. I have checked the DB Bahn website and there are ticket for the regional train, connecting with the bus for 29 euros. Do I need to pre buy tickets to get this price or can I wait and buy the tickets that Saturday when I arrive in Stuttgart? We fly standby so I like to leave my plans flexible when possible in case the flights go bad and we don't actually make it to Germany that day.
And one more question. I don't see the connection time to switch from train to bus. Will this become available when I actually purchase the ticket?
