Hi! My fiance and I just booked our wedding on a yacht going around NYC for 10/10/10!

We’re going to do the ceremony and reception on that yacht, so I was wondering if anyone has any experience with yacht weddings? This yacht has 3 floors (bottom for reception, grand stair case to middle foor for cocktail hr, top floor outside)… I’d love any yacht wedding ideas for photo ideas, cool things to do to make it special etc… Also, if anyone has any photographers with yacht experience that would be great to! :)
