'BACHELOR' COUPLE BEN & LAUREN B. ONE-ON-ONE ... in Paradise

'Bachelor' couple Ben Higgins and Lauren Bushnell finally took in their first post-show vacay, but even downtime for them requires cameras.

Scene: Gansevoort Turks + Caicos for 10 days at a $845 a night oceanfront suite.

Action: They spent the week snorkeling, taking dips in the infinity pool and getting rubbed.

Twist: No word on when they're tying the knot. It's been 7 months since Lauren scored Ben's final rose, but her wardrobe might be a clue that wedding's not too far off.
