I'm so glad you asked the question as I didn't realise some of the itineraries are different, I have just been working from the information we get sent and assuming it's correct. It can be so frustrating, as you ask a question in relation to the info you just got and the whole story changes again
We just heard back from our travel agent (who is wonderful and we could not have organsied our trip with her ) and she confirmed that we have 2days at sea not CC (oh well )
Now at least we know that it is the day at sea that is doubled up, so she has offered to follow up with our planner when she returns and find out why the 'fill in' planner was insisting that we have our ceremony on Thursday and not Monday.
As regardless of if its an onboard or CC ceremony, the earlier in the cruise the better, as I would love some time to relax too
