Did the Murcia-Cartagena tour when our ship docked in Cartagena . Totally worth it. Liked that our guide gave us the option to do a little more walking with her in Murcia and then grab quick lunch , or stop and have leisurely lunch. ( btw, if you go on a Saturday, you will see weddings in both Murcia and Cartagena) . She showed us the Roman sites in Cartagena from vantage points...then described how to go inside (fee applies) if we chose to. ). We also went with them to the Alhambra when we docked in Malaga.
