That definitely adds more cost which is likely a non starter. My answer to that is why? People who dont want a dome want the weather advantage against Miami in December/January. Would you open the roof if it was 20 degrees and blowing 15 MPH with some snow? If not then what is the point, cover it for bad or mild weather and keep it open when the weather is nice? To me, its dome or no dome, the retractable thing you see in the south.
