Last year was my and my wife's first runDisney race as well. We're coming again this year too and I can't wait. Assuming you're staying on the resort there will be people working at the bus stops who can give guidance when the pick up times are. We also did the Wine & Dine 5K and HF in October. My wife and I didn't care about getting to Epcot early and waiting around like we did at the SS so the CM working the bus stop at the Food & Wine told us the time of the 2nd to last bus that was departing from our hotel, which was the Poly. We're also in the coral F too, so again we weren't too concerned about where in the coral we should be. The race had already started by the time we got there, which was fine by us. They start the race at whatever time is listed but as too what time your daughters will start depends on their coral placement and where they want to be in the coral. If they want to stop for pictures in the race, I can see why this would be important especially if they're in a later coral. My wife and I are not picture people, though I do wish I stopped and got a picture with Scrooge McDuck at the HF in October. Last year we left BRV before 4 and were there by 4:30. This year we're at the Poly and I'm going to ask the CM the times again because I liked our approach much better at the Food & Wine than I did at the SS. They do sell food and coffee at Epcot too and there are plenty of portapotties and water stations as well once they get through security.
