I cannot clarify (I know this law exists in New Hampshire, but was not aware it was in effect in Massachusetts).
I did email Henry about this earlier today. He has other reasons to be in touch with the hotel soon, so he will discuss it with them over the next day or so.
Sorry to be a bit quiet on this, guys; it's busy over here! But I am checking in on the forums daily, so if you have questions or concerns, post 'em, please.
