How do I compare the large San Antonio hotels for my team?
Look at room count, location, nightly price, and on-site features like meeting space. JW Marriott San Antonio Hill Country Resort & Spa (1002 rooms) and San Antonio Marriott Rivercenter on the River Walk (1000 rooms) are close in size, so location and price may decide it. Engine lets you compare them side by side, including pre-negotiated rates where available.

Large hotels often include meeting rooms, event space, on-site dining, and parking. What's available varies by property, so check each hotel's details before booking. This matters most if your trip includes sessions or group dinners.
