The airfare I've been watching for the last 4 months dropped $100 per person last week, so I decided to call ABD and see how many people had booked our trip. I was told it's at 14% capacity. Not sure exactly what that means, but it sounds discouraging. I asked what the minimum would be to avoid cancellation and the CM said there is no hard and fast number. The tour director (maybe not the term she used, but something like that) would decide as we get nearer the departure date. That sounds reasonable. I think she was being purposely vague, which is okay since I'm just going to hang on and see what happens anyway. I'm guessing 14% is 4 or 5 people at the most and possibly just me and DS. I decided not to book airfare yet (our trip is the first week of June). I've read on the Dis board that some adventures have gone on with as few as 12 people. I'm sure it depends on the trip, but I'm curious about what you folks may have experienced with cancellations or what ABD may have communicated to you about minimum bookings.
