Tika,
Welcome to Luxury Cruise Talk. This is a great place to vent your feelings about this stuff. Hope you will post often!
I got the Baltics mailer today with Radisson logos, et al. For at least two years they've talked about re-branding. How could their marketing department not plan ahead?
I worked in Banking during all the mergers and acquisitions during the 70's and 80's. We routinely went through and destroyed tons of collateral, regardless of cost, because we did not want the old names on the marketing pieces. And if we had some regulatory piece with the old name, we had stickers to at least put over the old name.
