I had a very hard time keeping my hair from frizzing when I was in FL, mexico, and a cruise last year because they were all so humid! I've heard jessicurl products hold up well in humidity but I'm not sure if you use them or not. What you have sounds like it will work pretty well, but I'd bring a small bottle of your own conditioner or leave-in b/c both the cruise and mexico trip did not have conditioner in the rooms, and in FL it made my hair greasy. Products that were thinner but had a lot of hold worked well because my hair went flat so easily. Have a good time though and just remember that the messy bun look always works well in warm weather!
