A 10kw level 2 charger costs about $2k to install and uses about $1 an hour of power. A 250kw DC charger costs about $50k-150k to install and uses about $30 an hour of power running full tilt. Way lower upfront capital costs and way lower potential for abuse.
In places where people stay for multiple hours, there's a huge argument to install about 25-50 level 2 chargers and make them a free perk instead of one big fast charger. Less complexity, less potential for being blocked or vandalized, etc.
