Many people will already know this, but it is worth mentioning: Allure of the Seas will spend the 2015 summer season in Europe. She will be doing a programme of 7-night cruises, from Barcelona, calling at Palma de Mallorca, Marseilles, La Spezia, Civitavecchia, and Naples. (I’m not sure about that order – Palma would fit better between Naples and Barcelona than Barcelona and Marseilles.)
I gather that the cruise will also be available as a round-trip from Civitavecchia as well as from Barcelona. That might be a better fit, in fact – given the travel issues at Civitavecchia, I think I’d rather have a cruise day at Barcelona than Rome.
