One of my girlfriends left her 2 in the AKL Lions Club, or whatever the drop off place is called, and went to dinner. Her kids had a ball. She is very picky, to the point of neurotic. If she liked it, I would trust it. My guess is they are all the same. I don't know anyone who has used the in-room sitters, though. Just a thought, but maybe allearsnet.com will have reveiws on them. They seem to reveiw everything else!
I was wondering the same thing myself. Also, these "Drop-off" spots, are they areas that can be well seen. I'm always leary of these things - I don't know who these people are and what they do when I'm not around. Ya know?
