Okay, sorry to start a tipping post...hopefully this won't be as controversial!
We are planning on hiring a babysitter through Kids Nite Out, and wondered what you usually tip a babysitter. We've never paid for one...always had grandparents available at home.
Also, if anyone has used this or any other babysitting service, any feedback is appreciated! (We are not staying on-site at Disney, so the group sitting isn't possible. We'll be at a villa)
