I think RSVP has a great product, but I think they are missing the itineraries that appeal to a boarder audience. Atlantis seems to be selecting the ships/ports that more people are attracted to IMHO. Two examples are the recently opened up New Zealand/Australia cruise that sold out after a month after going public, and the upcoming Med cruise.
I like the idea of two companies, albeit I prefer two different owners, but it would be a shame if there were only one company going forward.
