"So, if you are suggesting that you have two distinct Oceania invoices, each with its own booking number (upper left hand corner) and different Oceania cruise number (right upper side of the O invoice) for adjacent 7 day segments, someone screwed up."
Not suggesting, stating this is what we bought and received.
Because of this thread, I checked with Oceania and TA yesterday; our B2B (NYC-Bermuda-NYC-Bermuda-NY) 7day/7day purchase it is considered two distinct and separate voyages and will be awarded two credits. BTW - Both Oceania and TA stated this is not considered a 'Custom Cruise'.
Thanks for the info. Another thing to consider when I retire and DW and I start going on longer cruises with Oceania.
