Originally a series of super-slick guidebooks, Mr & Mrs Smith have gone online to spread their special brand of sexy travel. Billed as the definitive boutique and luxury hotel guide, this site will provide inspiration for a weekend – or more – away in a top-notch love nest. By becoming a Mr & Mrs Smith member (from £10 a year) you receive perks at recommended hotels (free champagne, extra spa treatments) and great offers. A recent offer is reduced rates at the divine Dylan Hotel in Amsterdam.
