To obtain the necessary meeting and exhibit space, COSM must commit to using a minimum number of guest rooms. If that commitment is not met, COSM will incur significant financial penalties, which will have a major impact on its future programs. By booking your room under the official COSM room block, you help COSM meet its hotel obligations. We thank you in advance for your assistance.
