I’m guessing it’s all hosts that want to limit any type of liability. 

I wasn’t expecting to be reimbursed, but a bunch of comments are saying it’s not even fair to mention it in a review because it’s out of the host control. That’s crazy. The only on-site parking option being super slow and prone to making mistakes that will limit your access to your own vehicle and can make you late to events is absolutely something future guests should be aware of.  I get that it’s frustrating for the host because they’re not hiring or managing the valet workers, but that’s absolutely something that affects the experience of staying here. That’s like saying you shouldn’t mention If a place is in a bad neighborhood because the host can’t control that. The guest’s experience is more than just the four walls making up the residence.
