I am now on my third laptop and got through without stitch interrupting. Put everything in my cart, got to the checkout page and it keeps telling me to try again later. "Online checkout is not possible at this time, as our system is temporarily unavailable. Please try again later."
In another screen, I tried to modify my existing reservation and Mickey told me to sit tight for two minutes, don't hit refresh! and then he cycled down to one minutes and started over for the last ten minutes and finally the dwarvees showed up and said we're working on it.
All the while I'm 45 minutes into my hold time of 2hours.
