Our first cruises were on Riviera and Marina, both commencing in Barcelona. We chose this cruise to see Rio and escape the cold Canadian winter. Wasn't Sure whether the smaller Sirena would be as nice as Riviera or Marina, but I liked it even better. Beautiful European decor and all the same function rooms including a library to die for! The balcony stateroom was slightly smaller than Riviera and the bathroom has shower only but this was OK as far as we were concerned. First few ports...Rio Grande de Sul and Porto Belo were unimpressive but sailing in to Rio past Sugar Loaf at 5 am was a thrill of a lifetime. Food was wonderful, entertainment entertaining, shore excursions overpriced and not well co-ordinated by Oceania with local tour providers. That is my one criticism. That, and they should engage more qualified onboard lecturers in my view. but I cannot imagine cruise lines more luxurious than Oceania, certainly not better cuisine. The food and the libraries on Oceania will keep me coming back.
