We did this cruise in August, and there was six of us. In Athens we walked to the metro station which is a little walk but okay. The metro takes you to monkastrati where you get off, walk out of the station into square, walk to main road and turn left, you will find a bus stop for the athens sightseeing tour costing only 5 euros. This will take you all over athens enabling you to get on and off as you so wish. Once you have purchased this ticket this will give you free travel on the metro for your return. We were very tired on return to pireus and found a bus back to the port instead of walking, it was across the road from station.
In Dubrovnik do not use ov shuttle, there is a public bus just outside and takes you to pile gate where ov also drops off. In Corfu we hired a minibus with another family so can't help you there. Cephalonia is lovely, we stayed round the area. Didn't stop at Katakolon due to fires, and Heraklion depends on when your flight goes, we were on for 2 weeks and went to local waterpark again by public transport, bus station is a 10 minute walk away to the right of port, buses to beaches etc. Have a great time we did.
The ship will dock in Piraus which is the port for Athens. For this one I would suggest you take a taxi, which are always around the dock area, but negotiate the fare with the driver before you get in. I am doing a cruise in this area at the same time on a different ship and past experience tells me to research on the internet, get a map, follow links to puplic transport, and you can get yourselves around. If we meet up in any port and I see 5 Brits ranging from a babe in arms to a fit 70 year old, I'll say hello.
What would you expect to pay for the taxi and how do you get back.
Dont know if your back or still waiting to go, but I'll send this anyway. My hubby and I went on this cruise 20th sept, Dubrovnik is excellent a lot of walking is involved especially if you walk round the city walls as we did it was excellent definately a highlight of our trip and the views are breathtaking, but be warned there are a lot of stairs to navigate and its very narrow in places, not sure if you would manage with a small toddler you cant use a buggy here! we got the OV shuttle bus cost us £8 each but you might be better getting 1 or 2 taxis, dont even try to walk the roads are very busy. Corfu and Cephalonia were ok, easy to walk from the ship though not much to see and do, so maybe you could think about an organised excursion depending on the costs. Katakolon is a waste of time as its only a half day visit and only has 1 street, so get off stretch your legs have a cool drink then its time to leave if you can be bothered. Athens is a mega busy city and the traffic is awful, if your going to the Acropolis its dodgy to walk about, again due to mass crowds, lots of stairs, potholes and marble tiles underfoot making it very slippy, you need to watch were you are walking here and again I think it might be dangerous for such a young child, you cant use a buggy here! but we loved it, it is a must see, so its up to you, my tip would be to go in the early afternoon, I know it will be warmer but most of the cruise ship tours have been in the morning when we went it was madness and far to crowded. By the time we were leaving it was so much quieter and plenty of room to move about. Hope you have a great time, from Cathy, Scotlan.
