I like the changes since they are more interesting to me than bocce ball and glass blowing, but the obvious fact is Celebrity looked at the Lawn Club and saw a lot of non-revenue generating space. Kudos to them for going with something new though, and also with things that fit perfectly with the lawn theme.
Although Dan Hanrahan said the Corning deal will remain on the first 3 ships of the class, I'd be stunned if they weren't eventually retrofitted if results from Silhouette and Reflection support it.
