DH and I have two check ins for the week after Thanksgiving. I was able to check in on my iPad for both the studio at VGF, and the 1 bedroom at VWL. So, somehow this is related to my friends and pins.
I am happy I began this tread because I had not entered correct addresses for everyone, and now all is correct. So, they go to the desk, check in with their correct IDs and all is good.
