Yes - cruised with RCl and usually the stateroom attendant leaves a newsletter every night in your cabin with tomorrows port and there is a small map of the town etc.
Yes, you will get map - usually clearly indicating what shops they suggest you patronise!
To avoid the 'shopping map' there is usually a tourist info stall set up near the bottom of the gangway or a stand inside the terminal building you walk through with freebie local tourist maps. These are always a better option.
If you want to study what is outside of the town area then just print a map off the net. The ships will give you the main town map but not much usually outside of that. You will also get Port Lectures which do cover the main sites in the town but they also cover shops which RCI would like you to visit. You will also get a large amount of other information by googling "name of destination" tourist. There are many web sites which do good service this way but I like "Virtual Tourist" for honest imformation and if you couple that with cc boards you will be far wiser. .... Neil.
Very easy to DIY if you only go to this site that I direct every one to - Try google and 'cruise ports call boards' - the first result will give you all the info under the Europe section
And have you joined the meetandmingle to converse with your fellow cruisers?
