@Aaron Washington Congrats on getting up and running! Like @Michael Baum and @John Underwood said, this is a highly competitive area and I don't typically recommend going into a neighborhood that isnt a resort. Back when This community was built, it would've done very well, but when the resort communities came in, it made it really difficult to compete with.
I also agree with about the photos, you need to hire a professional, you don't even have lights on in many of the photos, it looks dark and dreary, plus the dead grass... People are coming to Florida for fun, sun and something different than they have at home, your photos should get them excited. Although you put some thought into the decor, IMO, you need to do much more to get people's attention. A few stickers and comforters aren't going to stand out. I'm not trying to rip into the work and expense you've done, but for not much more per night, I can get something really great with more bedrooms across the street in Championsgate, Windsor or Solara.
I'll jump in about the grill too, that's way too much, especially since your title says "Pool & BBQ", but I have to spend extra to get the BBQ part. I'm in the camp of not nickle and diming, but if much of your competition is doing it, I get it. It the same for pool heat, that though, you can charge by the day if you have it set up to be controlled remotely. Side note, next time make sure to get a spa, homes with spas rent much better than just a pool alone.
Wish you the best of luck!
