As a pet owner, what would entice you to attend a veterinary hospital "open house"?

The emergency hospital I manage is opening a brand new facility and we need to get the word out (better to know about the new site in advance rather than during a crisis). I’m starting to plan the Open House celebration and so far I’ve got a local rehab organization that will release one of it’s rehabbed raptors during the event, a local exotic animal rescue organization that will have some of their animals present, the police department doing a police dog demo (since we work on their dogs for free), and possibly the local shelter having a rabies vaccination clinic on site. edit: A local pet photographer will also be exhibiting his work, and we’ll be grilling hot-dogs .

As a pet owner, what sort of things would bring you out to see a new hospital? What would pique your interest? Any great promotional ideas that I can swipe?
