We have completed 5 cruises, 3 on Nautica back to back and 2 on Marina back to back in the last 18 months. Chose to return to Nautica for our 6th cruise of 18 nights as we found Marina impersonal and lacking the atmosphere of Nautica.
We had immediate problems with Internet access and speed. We both run businesses so Internet access is very important consideration.
We had free wifi access package for one device at a time which I think many many other passengers also had. We would have paid double the charged price if wifi to have slow but reliable connection. That apparently doesn't matter. No how much you are prepared to pay apparently you get nothing more.
