We've sailed on the Oceania's Regatta three times. Our first two experiences were very good, but the last one was not.
We were on the March 2011 Regatta to the Amazon. If you have read Little Red John's review, he really sums things up nicely.
We had several problems: Like ports dropped or changed. Upon boarding, we were told the Tobago stop was changed to the Port of Spain. Oceania knew this well before our cruise, and could have informed us prior to our departure. Many passengers (including us) had private shore excursions planned. Our stop for Devil's Island was skipped, supposedly because of the 3-5 foot swells. The Captain zoomed passed it before we were even aware that we had passed the island. He finally informed us that we wouldn't stop when we were nearly an hour past the island. We would have at least appreciated the opportunity to take some photos from a distance. We had 8 hours scheduled for this port, there was plenty of time for him to wait to see if the seas would calm down. Devil's Island was one of the reasons we booked this itinerary.
Then in Dominica we took a ship's whale watching shore excursion. The boat was overbooked and we ended up giving away our seats to some elderly people. The seas were extremely rocky, and one lady fell down. We stood for over 4 hours, trying to keep our balance. We immediately asked for a refund when we returned to the ship. The shore excursion desk person was very nice and said that she had received several other complaints. She couldn't issue a refund because she had to send the request to Miami. After a few days, we were informed that Miami denied our refund.
When we returned home, I wrote to Oceania explaining our issues. They said they had contacted the shore excursion provider who stated that there were enough seats. Well, there were some seats INSIDE the cabin where the crew slept. Now, why would anyone want to go on a whale watching expedition and sit inside the crew's quarters? Weren't we there to look for whales?
Oceania's offer of $300.00 for a future cruise is so insulting that I wrote again to request a refund or some sort of acceptable compensation. To date, I still have not had a response.
Having taken over 25+ cruises, I think we'll stick with Princess or Celebrity. We can have a full suite for what we paid for a Penthouse Suite on this unpleasant cruise.
