In the hospitality industry, the Best Available Rate (BAR), also sometimes called the Best Rate Guaranteed (BRG), is the lowest non-restricted rate that a hotel offers to the general public for a specific room type on a specific night. Unlike "corporate rates" or "member-only deals" which require special credentials, anyone can book the BAR. It is a "dynamic" rate, meaning it fluctuates based on supply and demand; it might be $150 on a quiet Tuesday but $400 during a major city convention. The BAR is typically the baseline used for all other discounts; for example, an AAA or Senior discount is usually a percentage taken off the BAR. For the traveler, booking the BAR often provides the most flexibility, as these rates are usually "fully refundable" up until 24 or 48 hours before arrival, unlike "Advance Purchase" rates which are cheaper but often strictly non-refundable and non-changeable.
