Considering holiday cottages are generally sold on the visuals then it’s the perfect site for rotating images.
Granted it can be done badly but if the views & décor sell the place then IMO it would be silly to dismiss getting a sample of this in front of the viewer as early and simply as possible.
By placing the images in a gallery only you’re forcing viewers into spending far longer on the site / more clicks and risking them never making it that far.
Remember the average site visit is measured in seconds, you need to capture people instantly to make them look further.
