Wow! I feel like a pro. Booked on Rome to Athens in April 2023 and did a ton of research. Originally booked with Oceania, transferred to TA and got a $600 OBC and OB Gratuities paid for just for the transfer.
Then took the Beverage package which we will upgrade on board using some of the OBC
Next waited for the air to come through with deviations for day before and day after cruise and looked at hotel offerings through Oceania.
Said no way, took the $1100 p/p refund, booked my own air and my own hotels which was several hundred dollar savings from Oceania when all fees were factored in.
Having just read your post, I'm pretty proud of myself!
