I thinking more about when the tanks are filled. Admittedly, it's highly unlikely, with employees wearing masks, and all the filtration and moisture removal that happens in the compressor on the way to the tank. However, unlike small dive operators who need to get back up and running ASAP to stay in business, this is far from WDW's primary revenue stream, so Disney can afford to be more cautious about it and wait. I hope I'm wrong, but Disney's focus right now has been on maximizing revenue while trying to keeping risk low. Getting an extra $180 from at most 24 people (out of tens of thousands) per day six days a week is less than a drop in the bucket of WDW revenue, so it's not likely to be at the top of the priority list, and I have a feeling that small niche tours like DiveQuest will be among the last experiences to return.
