When I finally emerged from the bathroom the alarm seemed to have reset, so no worries. But that was not the case. As I was checking out the desk manager said, "Ah, room 207, you set off the fire alarm this morning. You forgot to shut the bathroom door when you warmed the shower." Resisting the urge to comment on his comment, I simply smiled and said, "oops, sorry."
hopefully I didn't awaken any of the other guests. The final departing words from the manager were, "have a lovely day famous 207."
