Ireland or Norway

Norway will probably be colder than Ireland, but both will be fine for tourism. Depending on what part of Norway, some may have snow/ice but Oslo should not.

Are you on a really tight budget? While Ireland isn't cheap, the prices further north in places like Norway, Iceland, Sweden for everyday items, food & drink, are considerably higher. You may want to compare lodging, gasoline, sightseeing admissions, restaurant meal prices, etc. to help you make a decision if you are on a strict budget.

Thanks for your help. I have not looked into cost as of yet as I am still in the pondering stage.
