There's not a lot I can suggest that you won't see explained better in any tourist guide as I don't know the areas you are visiting well. What I would suggest is be careful of security for pickpockets etc as its their hunting season. Don't leave anything exposed in your car etc.
Isa is sitting with me as I write and she adds to watchout for new driving rules: basically headlights on motorways and dual carriageways, wear a seatbelt, don't use phone without handsfree. Police are very strict at the moment enforcing the letter of the law with a points system on license, as a tourist you would probably get away with it , but if not you might be prosecuted in your home country - exact interpretation is not clear yet.
Enjoy your holiday - contact us if you make it to the north.
