Really depends on whether movement affects you. It can get a bit bumpy through the North Sea but more times than not the Baltic is pretty flaccid. The Millennium Class ships sail well and I would have no hesitation in being forward remembering that there is still quite a few yards of ship still in front of you and I would go for a balcony which I don't think is overlooked in 6016. So there you have it play it safe but tucked away in the 3000,s or enjoy the views, and there is a lot to see in the slightly more adventurous 6000s. regards. .... Neil .
