Anyone know what the third new nook miles is?

I'm stumped

edit: by third I meant the middle one in the row, I unlocked the hotel room and diy ones

The third one out of the 3 to unlock ? That one is when you make certain amounts of DIYs and hand them over.

Not that one, the one between it and the hotel room

I haven't gotten it myself just yet, but the achievement you're asking about is tied into inviting any tourists on your island to your hotel.
