We just got back from our first FE experience(11 day christmas cruise) and can answer how it was run on our cruise. We had 65 rooms in the group. You delivered your 1 gift per room at some point throught the cruise, your choice on day. Some people give one gift per person, some do one gift per stateroom. So on our cruise we brought 65 gifts(a whole suitcase).
They talked about splitting the FE list into two groups(because of the size), but in the it was decided to keep a single group.
It was a great expereince, and am looking forward to the FW on this cruise.
