I’m on the same cruise (Southampton to Ft. Lauderdale) and I’m seeing the same speeds — 3 mbps down, 0.7 mbps up. So far, it’s handled most of my tasks without trouble, so I’m happy.
Taking a technical bent:
— Regal Princess was using SES service 2 years ago, and it was getting about 0.3 mbps.
— Regal has since switched to Starlink, which appears to be holding 3.0 mbps pretty consistently.
— Compare this with Sun Princess, which was built with Starlink. The speeds are better there because it was designed with that in mind.
— Speeds will depend to some degree on latitude. Ruby Princess (still on SES until this month’s drydock service) was getting speeds above 5.0 mbps in the tropics, but down to as little as 0.1 mbps in the North Sea. I trust Starlink will be more consistent, but should also improve as SpaceX launches more rockets.
