I have it on very good measure that OC and carry in general is allowed on CdA Resort property. The only no gun policy they have applies only to the employees, not to guests. He couldn't provide you with one because there is no written policy about guests possessing firearms.
FWIW, I have been OCing in and on the CdA Resort's property for about 4 years now, including inside the security office. Never had an issue with the rent-a-cops there.
