Think I know the answer, but......
Our only 2 Oceania cruises were on Riviera in the Med. We are going to Bermuda on Insignia in a few weeks.
Can't say enough good things about our Oceania experiences so far, and have a Marina cruise booked in Sept Amsterdam-Lisbon.
I assume the Insignia Bermuda cruise will be a completely different Oceania experience for us. More children, more of a party atmosphere, perhaps less well traveled passengers??
If so, that's fine. Just mentally preparing myself that this will be not the Oceania we have come to love. Refurbished ship and the usual fabulous food will be great.
