Thanks, that's how I was feeling too. I am sorry that her son got lost, no one wants that to happen on vacation. But again, if he can go to e-night alone, he needs to be able to get back alone too, and not just provided that he takes the same path as always. 2:15am can be confusing no matter what path you take, especially at the Poly with all those trees. They do have resort maps posted though to help those who are lost, and I'm sure the bus driver would have helped if her son had mentioned he didn't know where he was. Even if he just directed him to the GCH. He could have found his way from there or asked a CM at the front desk. The ttc is very close to the Poly, in fact it's the reason we're headed back there in April--for the location. Guests going to/from Epcot walk from the Poly to the ttc and back all the time to avoid switching monorails. I'm sure if the boy told the driver he didn't know where he was he would have helped, otherwise he probably just assumed he could get back to his room.
And I think the poster who asked about the cell phone had a valid point. He could have called you for help. You said 'what was that going to do for him" but it could have done a lot if he had used it. He could have called to say that he had to take a bus to the ttc and was confused. That would have solved the problem of getting lost. It's always good to check that your child can find his way around the resort very well before you let them out on their own. Like I said, when I was 15 (yes, a teenage girl) I was allowed out alone there, and my first time was at night going from the boat dock to the ttc to get a monorail to Epcot. After that, we always walked to the ttc to get to Epcot to avoid the 2 monorails, which made me very familiar with getting to our room from there. At that age, however, I would never have been allowed to stay out till 2:15am by myself--even though I could easily find my way back to the room.
Maybe and idea for the future would be to send him out with a resort map. That way if anything bizarre happens in the future he'll be better prepared to avoid such a bad experience.
