Which SPG hotels are especially convenient to one another for the purpose of hotel hopping without really interrupting your travels? This is not a new concept, but I think that the list has changed a lot with the addition of the Aloft and Element brands. In particular, I'll focus on some which are perhaps similarly priced. If guests typically have a car, I'll note some that may be a few miles apart. The Aloft Brooklyn opens next door to the Sheraton Brooklyn next month. The Element Lexington and Aloft Lexington are next door to each other. The Westin Westminster and Aloft Broomfield are just a few miles apart. The Sheraton Charleston Airport and Aloft Charleston Airport are on opposite sides of I-26. Both are now Cat2 hotels! The Sheraton Charlotte Airport (Cat2) and Four Points Charlotte (Cat1) are about 7 miles apart on opposite sides of the airport. The Four Points Charlotte Pineville is a few miles from the Four Points Ballantyne (which is behind the Luxury Collection's Ballantyne Resort.) There are several cities that have many obvious options that could be listed, though some would not be very convenient without a car. Some cities with multiple options: Atlanta (especially in Buckhead, Downtown, Perimeter North, or ATL airport) NYC (Manhattan) Chicago San Diego San Francisco Seattle Edited to add select contributions from others below: Link - The Sheraton Palo Alto and Westin Palo Alto are right next to one another.
