Some points I thought were interesting:
The proposal is about 15% of every hotel and short term rental/AirBNB stay. Or as they propose, start charging people for pickleball lessons.
(I have no idea what that is, but it seems to be a thing for locals, who are already suffering so much) I do agree that the $1 to climb Diamond Head could be increased, and was surprised to see that earlier this year.
But as you note, they have to find the right balance of charging tourists vs locals, and cutting government spending vs relying on aid. If they don't, they risk a significant reduction in revenue from tourism, which may be a long term goal but will not aid in recovery in the short term.
The longer this goes on, the more likely people are to have already booked summer holiday plans. Even if they announce a plan to reopen on some date in July, for instance, they won't get that much interest. Also, resorts require significant lead time to reopen and prepare.
