How necessary is to bring a suit with me?

Hello:
    I'm Efrain from Mexico, And I've got a Doubt, I'll be on Orlando on July 18th, and we know the weather gets warm in that season, so my Question is. How Necessary is to bring a suit with me and how many times are we going to use it once we get there?.

    I'd like to bring formal clothes with me, instead of suits, Could I?.

I really appreciate if you help me with this doubt.

Thanks

well, you do need formal clothes for some of the classes the first few days...but it doesn't need to be a suit...nice pants (no denim!) and a shirt are fine...

 

Thank U so Very Much.... Flavour... I really appreciate your help...
