Biggest Hotels in Maryland

In Baltimore, the Renaissance Baltimore Harborplace Hotel tops the list of biggest hotels you can book through Engine in Maryland, with 622 rooms. Close behind are the Baltimore Marriott Inner Harbor at Camden Yards (524 rooms) and the Hyatt Regency Baltimore Inner Harbor (488 rooms), both also in Baltimore. Teams planning conferences, meetings, and multi-day events use these properties when they need enough rooms under one roof for a large group.

Large-capacity hotels matter across Maryland because conferences, corporate events, and group travel often need dozens or hundreds of rooms in one place, and Baltimore's Inner Harbor area has built up a concentration of properties that can handle that scale. Maryland is also home to government agencies, universities, and health and research institutions that draw regular meetings and conferences from around the country. These hotels serve organizations of every size and industry booking room blocks, from small teams to large groups filling out a full property. Engine lists these hotels alongside the rest of the state's inventory, and for a stay of 9 or more rooms, Engine Groups handles the booking, while stays of 8 rooms or fewer can be booked self-serve on the platform.
