You cannot assume that any given hotel is owned by the corporate parent - many are owned by franchisees, so the "its a big company" argument is not necessarily valid--just because there is a big name on the front of the building, the establishment might be a small business for all intents and purposes.
Beyond that, I am really not sure what your complaint is here. They put in a charger at some cost to themselves. They were thoughtful enough to put in a HPWC instead of going the ChargePoint route, so I assume you benefitted from faster charging. And they charged you for another $5 for a second charging session after you had checked out. Expecting an establishment to offer services when you are no longer a guest is not, IMO, reasonable. Posting a negative review specifically referencing charging is not helpful as it reinforces the image that we EV owners are whiny and entitled.
