Yes. Compare a Europe Itinerary on Navigator to Voyager.

I just did the math on a Baltic and edited my post. Same time.
Voyager to Insignia. $400 a day different per person. I factored how we drink and tips. More ports on O. For me, this is a no brainer
I would have argued differently last month, but, there was such a small difference in quality onboard, that we will book our next cruise - Baltics with O - even if we pay for internet and wine.
