There is another option the characters can use, other than spending the night in the Library, which has no bedrooms. Yes, they can make do, sleeping on the floor in the private area, or on the furniture, maybe even conjure up something comfortable. Or...
There is the Jolly Madison Hotel a block away. It is the early, early, early, morning, but then in midtown Manhattan, people are up and about, some are first coming back from a night at a club, and the hotel has a night desk clerk.
And best of all, the Library has a permanent account here, as this is three minutes from the Library walking, and is used for VIP visitors.
It has a few things the library does not: showers in the rooms, and free breakfast.
(There is actually a closer hotel- next door, wedged between the Jolly Madison and the Polish Consulate is the Morgans Hotel, but despite the name it has no relation to the library. But, it is smaller and very expensive, so the library went with the Jolly Madison)
Either way, the characters can get a night's sleep (either a good one or a so-so one, depending on their option) and they can meet with the gang in the morning. Very late morning, in the Library.
Tiatha is here too, as she has been working on the Thanksgiving Invitation List Project.
The Nisse look quite tired... but there is the smell of coffee.
The Jolly Madison Hotel. Just to the right is the Morgans Hotel, to the right of that the Polish Consulate, and then to the right of that, across the street past the bus and taxi, the Library.
