We are a retired couple and chose this cruise because of the ports it called at - bad choice of ship.
The embarkation in Venice was awful with everybody pushing and shoving to get on first.
The ship was okay but the public toilets on Deck 2 were disgusting - some were always blocked and out of order.
The cabin was ideal as it was at the back of the ship so no 'through traffic' to disturb you. The weather was good so we could sit out on the balcony and watch the world go by. It was a reasonable size with a king size bed and a settee, plenty of storage space and a nice bathroom which had a walk in shower. The only problem was the showeer had a shower curtain which didn't reach the floor so everytime we had a shower it nearly flooded the bathroom.
We have been to Venice many times so didn't take any tours.
The town was a walk away from the ship so we did our own thing.
Kotor was a lovely town but did not take any tour.
We didn't take a tour to Olympia but Kotor is a lovely town and worth walking around.
We loved Corfu and took the shuttle bus from the ship to the town. It worked very well and then we took an open air 'train' to see the sights of Corfu - very interesting history and a lovely town. The Greek people was lovely.
We weren't long in Dubrovnik so got the shuttle bus from the ship and walked around the old town - you can walk on the wall which encapsulates the city which would give you great views.
