As someone suggested in an earlier thread, it looks like you can reserve an itinerary until midnight of the next day if you choose one of the cash payment options. Go through the purchasing functions and when you get to payment method, scroll down to cash payments. It looks like there will be a small transaction fee depending on option. (and also an inconvenience fee from my standpoint) I'm not sure if Platt's are exempt from the fees or not. While not expedient, it looks like it is still a viable option.
