I went last week and the current situation is that it's open from 12:00pm till 15:00 then again from 17:00 to 20:00. Showings are every 30 mins during those time periods.
So yes, it's open but with limited operation, although you can turn up with less that 5 mins before the start of a show and still get in without much of a problem. It's still an amazing show and they've not cut back on the actual ride at all.
