The Fujifilm Instax Mini 90 Neo Classic is a really good choice if you're a fan of classic-style Fujifilm brand cameras. It comes with several different image modes like multiple long exposures, and it's a bit easier to use than other models with the same features. This FujiFilm camera prints the images on immediate film, a retro rewind move for the selfie generation, a nostalgic throwback for Millenials. This camera is the best-looking Instax camera out there. With its two-tone finish, and silver accents and your choice of either black or brown leatherette, it goes a long way to reinforce this.
If you truly care about aesthetics, don't forget about Lomography's Lomo'Instant Automat, which is a great camera in its own right and is also available in different finishes and special editions, unlike the Instax camera. The lens is the same 60mm f/12.7 design used in other Instax Mini cameras from Fujifilm.
Newer travel photographers might be used to shooting with a smartphone, so you'll find the angle of view to be a little bit tighter than your phone's main camera. If you want a wider angle, think about the Lomography Lomo'Instant Automat Glass, which features a brighter, wide-angle f/4.5 glass optic with a 21mm (full-frame equivalent) angle of view.
