Freddie is still around.
He only comes out about 30 minutes on a typical day and makes brief appearances at the Welcome Aboard Show etc.
There are times when he will not be on a cruise IF the "Funship Freddie" person (yes, there is a specially trained person who does him) has rotated off and the new person has not yet rotated on.
This happened on the Victory 2007 and just last month on the Fantasy.
(The only reason we know is because they send us FF schedule so that we can avoid him....youngest son has Autism and panic attacks around mascots.)
