depends on weather conditions and the contract with the sponsors who paid for it to b built all agree on how many times a year will they completely open the dome....they crack it open about a quarter of the way for air with the giant glass door opened as well and a full opening dome all the way open with tht glass door open.....weather conditions only determine if they keep it open or not it takes about 5 maybe 10 full min to open/close
Yes, they do.
I was there in mid July and it was closed. Mostly because of heat I think. It wasn't raining.
