It will be interesting to see if this is the case when Regal starts sailing out of Southampton on the British Isles cruises. As Cloudyrain says we don’t tend to do this much, maybe a happy birthday banner. However, I expect there will a good number of North Americans (certainly seems to be on our cruise) so it remains to be seen if this will continue to be enforced. Personally I can’t see any harm as long as nothing controversial is displayed.
