Put the call to action where the curiosity is
Most sites bolt the booking button to the bottom and hope. By then the curiosity has cooled. The best moment to ask is the moment they lean in.

There's a quiet assumption baked into most websites: that a visitor will read everything, get convinced, scroll to the end, and then act. Almost nobody does this. People decide in flashes — a photograph that lands, a line that names exactly what they wanted — and the question is whether there's anything to tap in that instant.
Desire has a half-life
Curiosity doesn't accumulate toward a finale. It spikes and fades. A guest sees the suite at golden hour and feels it; ten seconds later they're three scrolls past it, half-thinking about lunch. If your only "Reserve" sits in the footer, you collected the peak and offered nothing.
So we stop treating the CTA as a destination and start treating it as a companion. Where desire crests — under the room that sells itself, beside the testimonial that resolves a doubt — there should be a way forward.

Not more buttons — better placed ones
This isn't an argument for plastering "Book now" every 400 pixels. That reads as panic, and panic is cheap. It's an argument for reading the emotional arc of the page and putting the invitation at its high points.
The right time to ask is the second they want it, not the second they finish reading.
The numbers back the instinct: headline and offer placement optimisations routinely lift conversions anywhere from 27 to over 100 percent, and the lever is rarely a flashier button — it's a better-timed one.
A great page doesn't herd people to a single exit. It walks beside them and, each time they lean in, quietly says: yes, you can have this now.
