I still think that the encouraging people to book June 1 wouldn't have been so bad if they had extended that
free dining offer longer. Then at least you may have had people choosing later fall/winter months instead of trying to pick the least problematic of the offered months for their family.
For a lot of people July, August, and September are really not ideal months to travel to Florida. COVID-19 aside, June is probably the most appealing month to travel out of the ones offered when considering weather (heat and hurricane season), and then the latter part of the deal interfering with hopeful school year starts.
