The best airline I've flown was Virgin Atlantic from MCO to UK; the service was outstanding. So if Branson can carry that forward, he might have a real winner.
If they can bring that level of service to the Scarlett Lady then they might have a niche market space (adults only). The design of the public spaces looks really well planned (except that restaurant, Razzle Dazzle, with the WWI/II boat camouflage.......egads!). The rooms with the shared sofa/bed is not something that appeals to me. It looks like they tried to be novel in design/space, but looks cheap. Plus there is something about sleeping on a place I spent sitting that feels "off".
I am eager to see the actual ship reviews and how the guest experience(s) play out.
