Volcano Rainforest Retreat, Volcano, HI: In the secluded Sanctuary, light candles, make the Tibetan chimes kiss, play a CD of sensuous Indian music, and whisper words from a bedside book of meditations on love. As you snuggle under the Balinese-print quilt, you’ll feel a glow that comes only partly from the ornate cast-iron fireplace.

Hotel Cielo Rojo, San Francisco, Mexico: It’s all about foreplay here. Before you even check in, pour yourselves a shot of tequila from the hospitality tray.
