I'm traveling to Spain with 4 four friends in late May. We have apartments in Barcelona and Valencia. I thought it would be fun to stop in Tarragona for the day on they way from Barcelona to Valencia, but I'm running into a bit of an issue. We would really like to have a guide with us in Tarragona and be able to see the cathedral, the Roman ampitheater, and the Circus Maximus etc. But everything I'm seeing for this is pretty steep if you meet up with the guide in Barcelona.
Does anyone have suggestions for a guide we could meet at the train in Tarragona?
I'm also assumming we can check out luggage at the station as well for the day, but I thought I would write and ask.
