Lots of great suggestions, here are a few more to consider...

Four Seasons Anguilla - all categories except for the entry-level Resort View room include private plunge pools. Gorgeous beach and stunning crystal clear turquoise water.

One&Only Palmilla - Oceanfront Junior Suite with Plunge pool... Oceanfront Casita suites with infinity pools are even better. Swimmable beach.

Four Seasons Los Cabos - Ocean-View and Oceanfront room categories have plunge pools, huge swimmable beach, quiet, and a great place to completely unplug.

Four Seasons Punta Mita - Oceanfront plunge pool suite up on the cliff above Cuevas beach with beautiful ocean views, swimmable beach.

Four Seasons Lanai - No plunge pools but an absolute home-run honeymoon location and they have just extended the complimentary Lanai Air flights through 8/31/22.

Love them all!
