We just took the self guided tour with ipod We just wanted to get there and back without the hassles. "Princess" the bus tour guide was great giving a bit of history on the way there and back. The rug shop tour afterwards though hard sell was actually interesting and the rugs were truly beautiful all but 7 people disappeared when that part of the tour arrived.
This port is beautiful, unfortunately everyone was on strike because they were closing down schools so we didn't get to see a lot that day. We did the "little train" trip around the city which wasn't bad.
