Ive fished Canada ,California,Australia,New Zealand ,Norway,Italy,Portugal,Canaries,Florida,Cuba and many others.In the end if your choosing for sun and normal holiday stuff then your not going to be hitting the best situation fishing wise unless your very lucky.As ever research the area your going with google etc get local on the ground knowledge.Thing is with fishing is that we all have favourite types for me I would rather catch a 3lb codling than a marlin.If you like shore fishing for the cod etc go on a guided tour in norway,that would be my dream trip.If you like warm weather just remember the whole dynamic of whats available changes and boat trips can be a rip off .I lived in L.A for 4 years and took my cod gear over ...the fear on the swimmers faces when I was pulling out 5 foot leopard sharks was a sight to behold...would still rather have a 3lb cod on a freezing night mind,must be viking genes or something!Good luck where ever you go
