Jessie & the gang are staying at Kerami. This place still exists & I've read a bit on the history, it's interesting.
I wonder if it was Jessie's family who built the original house. I should really get in contact with the current owners as I'm sure that they would appreciate some scans of Jessie's album.
I'm not too sure about the "party" (maybe it was a slumber).
