Hmm, for a date three days after Canada Day? Don't know, @Paul154 .
I closed my calendar to July 15 and am considering closing the entire summer but will wait to see how the reopening of the province unfolds. However, if I were hosting on my own country's big day, or, like you, on @Gordon0 's wedding anniversary, I would keep my price up. Those who cannot afford to travel as usual, I think, will not travel at all. Those who can afford it, will come anyway.
I have nothing to base that on. I think I just don't want to give discounts.
