I just got to thinking, there's something I missed in the past about the bookings of SWGS. I imagined that only people who are serious about going will be calling to book. However, what I didn't think about are the fans who can't afford it but book it anyway just to be "part of the booking experience." They call time and again, wait on the phone for hours, talk to the CMs and ask tons of questions, score a reservation and put down a deposit on their credit card for a couple of weeks, then call back to cancel. It all costs nothing is great fun. Some do this on purpose, while others maybe subconsciously, like making a new years resolution: I will put down a deposit now and save money in the next few months to pay for this trip. But as time passes and no money is being saved, negative thoughts begin to invade the mind "I should wait till the reviews come out to see if it's worth it").
The proof is in the pudding. By next month, voyages in March will begin to require full payment that are nonrefundable and nonchangeable without a heavy penalty. By then, we'll know for sure which months are fully booked.
