To obtain the necessary amount of 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 and it will cause a major impact on the future programs that COSM is able to offer. By booking your room under the official COSM room block, you help COSM meet their hotel obligation. We thank you in advance for your assistance.
