Most high-end hotels reserve the top 20% of their inventory for direct bookings – which typically means booking over the phone. They don’t put these reserved suites on other third party booking websites or even their own site. This includes suites, multi-room suites, and penthouses. Suiteness works directly with each hotel and is the only place that you can book multi-room suites online. This is a great way for families and group travelers to find spacious accommodations that are not vacation rentals.
