In 1963, the savvy owners of the Cove Haven Resort in the Poconos unveiled their heart-shaped tub.

Like Elvis Presley and Playboy magazine, it launched a post-war phenomenon that defined a new era of pop pleasure: the honeymoon hotel. Destinations across the country were soon racing to catch up, installing not just heart-shaped tubs but all types of over-the-top design flourishes, from pink shag carpeting to immersive worlds worthy of a Broadway stage set, in order to create a sense of romance, fantasy, even adventure.

From the photographers and inveterate travellers behind the social media sensation A Pretty Cool Hotel Tour, Hotel Kitsch celebrates dozens of creative, nostalgic, one-of-a-kind hotels that span the heart of the Poconos and across the United States to Mexico, Spain, and the UK. Discover, in the middle of Iowa, a jungle room with fake trees and foliage surrounding the bed as if it had taken its cue from Where the Wild Things Are. Or Jules' Undersea Lodge in Key Largo where the rooms are reached by scuba diving. An Arctic Cave room at a hotel in Kentucky with its carved blue walls and not a window to be found. And on the California coast, the iconic Madonna Inn featuring 110 rooms, each themed and no two alike.

Along the way, authors Margaret and Corey Bienert uncover too many wild details to mention, including unconventional beds (a Cadillac, a clamshell, a sandwich), mirrors on mirrors on mirrors, in-room swimming pools, full suits of armour, and fibre-optic star ceilings.

While it's not a travel guide, every destination in Hotel Kitsch is open for business. Time to check in.
