I won't be back at WDW for a few months, but I was wondering if the best way to get to the Mine Train at park opening will be to go through the castle or bear right at the Hub and swing around toward Cosmic Ray's and the teacups.
Through the castle would probably be shorter, but until the Anna/Elsa craze dies down that could be extremely congested and borderline dangerous.
On that visit we will be entering the park on our daughter's CM pass so advance FPs probably won't be an option. At least if we go on an AM EMH day there shouldn't be any FP returns for the first hour.
