A photo gallery answers 'what does it look like'. A 360° tour answers 'what is it like to be there' — and that second question is the one that closes bookings.
Across the hospitality projects we've delivered, pages with an embedded tour consistently hold attention several times longer than gallery-only pages. Visitors self-serve their way through the space instead of bouncing to a competitor.
The practical advice: put the tour above the fold, keep the first node in the most impressive space, and label hotspots with plain language.
