Hi @AthyllaBastos,
I would advice to use a separate collection for Images, link it to Hotels collection so that 1 hotel can have several Images, but an Image belong to one Hotel
There are several options:
- use Image Slider component from the Marketplace
- use Image Carousel component from the Marketplace
- create your own gallery. I did a video here: Image Gallery examples (my first try :) )
There is another great example from @pford: Adalo: Creating a Rotating Image Carousel or Gallery with Unlimited Images
Hope this helps
