How Should I Thank ..?

Gina, If you've already emailed and received no response, under the circumstances, I think that's all you need to do maybe? That's just my opinion for what it's worth. Good luck

I agree.

As for knowing a lot of the story a formal thank you like Jenfer says only I would say "thank you for the short stay " It's a thank you and formal enough to get the point across.
Personally I think the email is enough and if they don't like it tough cookies. (mommy talking)
