Airbnbs and similar offerings are booked solid in and around the path of totality for Monday's total solar eclipse, per estimates from short-term rental analytics platform AirDNA.

• In fact, mapping out fully-booked cities paints an almost perfect picture of the path the eclipse will take as it crosses America from Texas to Maine.

The big picture: Millions of travelers are expected to descend on cities and towns in the path of totality.

• Hotels, short-term rentals and even campsites have been booked for weeks, if not months.

How it works: AirDNA collects daily booking data from over 10 million short-term rental properties worldwide.

• It looks at properties listed on both Airbnb and Vrbo, but de-duplicates listings posted on both sites "to give a true size of the industry," the company says.

The bottom line: If you haven't already made your eclipse plans — well, good luck.
