Uncle Bob is not coming back to run Carnival. Looks like he will primarily be sucking up to Travel Agents and trying to attract more first time cruisers.
Don't forget, Cahill was CFO under Uncle Bob.
Until recently, Uncle Bob was still on the Board of Directors of Carnival but for political reasons no longer is.
I don't see it as a long term relationship or that he will show up with a pocket full of miracles.
