The terms are different for US Future Cruise Down payments so hopefully someone with some experience will be able to answer.
For UK bookings they are only valid for a year, the cruise needs to be booked within that time, not taken. For US bookings it was 4 years.
They can only be used with certain fares (in the UK Cunard and Early Saver) so that could be a problem with your group booking.
Think it's best for the OP to speak with the Group's PCS
There are those who have, and those who have Yachts.
