Of the options famously offered by hip-hop group The Sugarhill Gang, motels are often the cheapest. They also poke a soft spot in the heart of nostalgia-lovers. Some might look down upon them, but a road trip wouldn't be complete without these bastions of terrible coffee and neon splendor. Last year marked the 100th anniversary of the first motor hotel in the world - the Milestone Mo-Tel in San Luis Obispo.
From the late 1950s into the '80s, thousands of motels proudly advertised their Magic Fingers - a little collection of vibrating electric nodes under your mattress that would give you a 15-minute 'massage' for 25 cents, inspiring creators from Kurt Vonnegut to Frank Zappa. Alas, their moment passed.
