How many photographs of bright blue sky, fluffy white clouds and turquoise water do you need? I frequently shoot B&W in the Bahamas and Caribbean. With color film, sometimes scenes in the islands pratically take themselves, but when you get home, the photographs frequently have a sameness to them.
I would definitely take a yellow filter, and highly recommend a polarizing filter and red filter. Just in case, I generally keep a Fuji recyclable camera with me just in case.
Looking through my vacation photographs, I have found that a disproportionate number of my favorites are in black and white. Oftentimes, the wonderful colors of the Caribbean can distract from the focal point of your photographs.
