How close to Bradenton do you need to stay? NOVA 535 in St Pete comes to mind. They actually do a masquerade ball there every October/November. It's a really cool venue and that have a great outdoor bamboo courtyard. Check out http://simpleweddingsflorida.com/nova535weddings.html !
Palma Sola Botanical park is an amazing location to have evets at such as weddings. I have seen pictures of it on https://www.propertywire.com/other_news/why-essay-services-are-so-popular-now/. They are beautiful.
