Took party to the inn, needed to rest my characters in slot 3 and 6 since they had used some spells.

Selected character in slot 3, then selected the "zzz" option, they rested, got spells back.

I was now back at the prompt to select a character to display options, I clicked character in slot 6 and was immediately informed that they had rested and got spell points back. There was no options banner displayed, no chance to inspect, it just automatically rested the second character.

I then further tested each other character in the party. It appears that once the Inn is visited, if you rest ANY member of the party, clicking on ANY other party member will instantly rest them without any options to do differently. The only way to get the options banner back is to leave the inn completely and then go back in.
