Crusiing with our CruiseMates group cruises is always a great experience. We always arrange an informal pre-cruise get together in the embarkation port for anyone who may be in the city in time to attend.
Once onboard, the first full day on the ship we organize another get together to enable everyone in the group to meet. Then there is also a complimentary group cocktail party to enable more socializing.
Our CM host on each cruise also organizes other events onboard like trivia contests, gift exchanges, scavenger hunts, etc. These are once again just to assist anyone wanting to participate to get together and socialize.
Generally there also ends up being a designated "informal" daily meeting spot, both during the days, and in the evenings where folks who just want to meet and visit know they can "stumble by" if they feel like socializing.
The cruise you're talking about.... the John Heald Blogger's Cruise will have some other special events with the ship's CD John Heald for this group.
Should be a GREAT time!!
