Wide Angle Lens for Angkor Wat?

Hey Y'all

I’m off to Southeast Asia in a couple of weeks and will be touring Angkor Wat and other temple sites. I would like to ask those who have been there whether a 24mm equivalent lens will be sufficiently wide to get encompassing images of the structures.

I am considering purchase of the Rokinon 7.5mm and then “de-fishing” the images or possibly renting an Olympus 9-18mm. Any advice would be appreciated.

Thanks.
