It's so nice when we get the occasional icy evening and I can walk out onto the patio and smell the plants and a bloom or two. Some of my plumerias bloom thru the winter. We have lights strung along the eaves, so I can see at night. The heaters keep it tolerable.
I did have a "hip high" hoop house to cover my in ground tropical hibiscus. I only had Xmas lights strung around them and they survived our winter and bloomed in the enclosure. They got really large, and I eventually gave them away.
We've gone thru so many remotes for our heaters. Just haven't found any that are truly reliable. Our winters are short, so we really don't need a big greenhouse, but I wouldn't turn it down if offered one for Xmas! I have a tiny one on the side of the house that's all glass. It's more a storage shed, tho. 'Too tiny for most things and on the north side of the house, but too cute to take down.
There's an article I wrote about constructing a temporary greenhouse along the fence line to cover my tropicals. My DH was away and I put it up by myself...except for the plastic, which my DD helped me with. I was pretty proud of myself, until I raised the plastic one warm day. The wind caught the rolled up plastic and carried it over the fence to my neighbors' backyard, pulling out one side of the PVC pipe as it went over the fence too. DH just rolled his eyes...
