Blessing at sea

[TrueBlueAngel]

Has anyone done a blessing at sea with a Thomson Cruise? Hubby and I are celebrating our 25th wedding anniversary next year and are doing our first ever cruise to celebrate on TUI Discovery to the Carribean. We have booked it through our travel agent, but we don't seem to know anything about it or won't until we board ship. I was told it was like a renewal of vows, which is what we want, but don't know what we need to prepare in advance, even down to our own words.

Can someone help or advise? Maybe your own experiences?

Thanks.
