For something special as your 10"th wedding Anv. , No WAY
I see your chain of thinking, and its a good thought.
If you could get a free cruise, and donate 2 hrs of your time, that would make a nice gift for your wife and you.
For something that special, I would go to a good TA (if you need one ,let me know ) and book a cruise for the 2 of you. ( If possible) Then you would have no worries.
The wife and I celebrated our 25'th wedding aniv. on the Conquest, and it was wonderful Theres no get away like a cruise Let us know how you come out.
Best of luck to you and yours;
