Certainly reading other websites with more locals posting, the tone is very different from here. The situation is presented as far more dire elsewhere, and more aligned with what other tourism dependent markets are facing.I would say if you redid the poll after July 31st, you'll get a different response. Unless you're just polling retired or rich people in which case keep out the tourist for as long as possible because now you don't have to share the beaches with anybody else. Those with dwindled life savings trying to decide if they should use their lower unemployment checks to pay for food or rent will have a very different set of priorities soon enough.
The challenge, as noted, is that giving only short advance notice for any change in plan will not result in immediate new bookings. I had a discussion today on the subject of a potential Japan bubble to Hawaii. The Japanese government is offering up to 20,000 Yen per day for domestic travel. Anyone who has travelled in Japan will understand the power of domestic travel in that country. So hopes for the Japanese market to return to Hawaii should be considered fairly low in the near future, with the exception of those who decide not to cancel already booked trips. The longer the period drags on without a decision, the more likely it will be that the Japanese cancel and book a domestic trip.
The other option is to expand the bubble to 'safe' feeder markets ie Australia/NZ, and to British Columbia. However, again the lead time to book a Hawaiian vacation is generally longer and it is not for most of you a spur of the moment decision. (I noted above that I recently flew from Japan to HI, which was just a weekend detour and quite common amongst my circle but not something most people do) And those places have their own challenges ie quarantine on return, discouraging travel, etc.
The reality is that any decision once made will have a ramp up time to see any significant benefits.
