Whilst it is good news for those who like adult ships, the refurbishments announced seem to relate to mainly cosmetic changes such as furniture, soft furnishings etc. rather than structural improvements.
As you said some time ago, bathrooms, for example are designed to last the life of the ship, and replacing them is really not feasible. And the bathrooms on Arcadia are already showing their age !
We were thoroughly disappointed with our cruise on Arcadia last year - so, much as we like the idea of adult cruises, we are not prepared to cruise on her again, despite the adult only benefit.
Goodness knows what state Arcadia and Aurora will be like in five years time.
