re: Greek cruise out of Venice, any help would be great

I dont really mean in regards to clientele but in regards to what the different lines offer. Sailing Viking will give you much different experience than sailing Royal Caribbean. If I am sailing Europe with my wife and daughter, we couldnt do Viking because they don't have kids, BUT, if it was my dad, brother and I we would go Viking all the way.

When you're in Athens regardless of the line you have to get off and tae a bus for hours from the port, that doesnt change regardless of what line you are one.

But, on Viking excursions are included so if you plan on alot of cruise excursions you may want something that includes those. If you don't plan on booking directly through the cruise line maybe look for a cheaper fare and look to add on an all inclusive alcohol policy, etc.

Almost of the lines that sail in Europe have similar itineraries but the lines themselves can differ a good bit from what they offer or where they sail from, cost, whats included, etc.
