I understand that there always can be issues, but I have sailed several times on the Rotterdam and the Celebrity Edge, both with Star Link. There were issues on both cruises due to legal agreements with StarLink and sometimes when the signal was blocked.
But when everything is working as designed should I expect the same level of internet performance on the Vista and Signature class ships that I have experienced on the Rotterdam. I’m not looking to run a business or attend meetings, I’m just looking for entertainment.
