MAST has held a limited amount of groups. See below for MAST Headquarter groups:
Group space is held under MAST. You book under your agency but into the MAST Headquarter group (MAST HQ GROUP). If you have any questions please contact Celebrity’s Group Department at (800) 437-4111.
If Gap points were available for the groups, maximum Onboard Credit has been held. OBC normally ranges from $25 to $50 per cabin on the RCCL groups held by MAST. Some sailings do not have GAP points so there will not be Onboard credit on the groups without GAP points. Contact Celebrity to inquire as to whether there is an OBC on the sailing/group you are booking into.
You may also contact Celebrity’s Group department directly to hold group space under your agency. Phone: (800) 437-4111 CruisingPower.com
