Mike,
They are a maintenance NIGHTMARE
The last club I was at had a dome.
A dome is as needy as an infant.
Lets talks about snow first:
The snow slides down the sides and piles up against the outer wall. Now you have to come in immediately afterward to bobcat and hand shovel the snow away from the base. That takes four men 2-3 hours, and you have to be on top of it right away - within hours - any time of the day or week, or else the snow will push so hard on the bubble that the fabric will split in multiple places. So you have to have a good team of guys on call 24/7 for this kind of work. That includes Christmas, your anniversary, your child's birthday party, whatever.
You also have to heat it. And the fan has to run nonstop for all of the time it is up.
And then at the end of the season when you take it down, it is too heavy to roll up and haul away, so you let it sit deflated. So now every time it rains you have to inflate it to get the water to shed off, but you can't get all of it off. So in the fall when you reactivate it, now you rent a couple of cherry pickers and power washers and 4 to 6 people work for several days cleaning the mold and mildew off of it. We had guys who would actually have to get off the cherry picker and walk around on the roof of it to clean it. HOW SAFE IS THAT? What is required to clean these things is absurd.
RUN FROM DOMES LIKE THE FRIGGIN PLAGUE!!!!!!!!!!!
If you have good people working for you in maintenance that you value, you would never buy a dome, because taking care of a dome will kill your people.
Every employee of our club hated the dome. And we all felt that it endangered our safety too.
