If you're talking about October 16th (and I think you mentioned that earlier?), the Epcot Monorail was down for most of the day, starting mid afternoon I think. One of the guide rails on side buckled/broke which shut the line down. I think I found out thru a twitter feed. As we were heading to F&W that night, we knew to take the Bus from GF to Epcot. It was still down when we left Epcot (around 7-8pm?) They had busses running from Epcot to the TTC. They brought in normal tour busses to help handle the crowd, which was nice as our stroller went underneath. From the TTC we boarded the monorail back to the Grand. I think the total trip was 1.5 hrs if we include wait time for the bus and until we were back in the room. I'm not sure why they told you to take the Ferry to the MK? They should have put you onto the Resort Monorail right at the TTC. That sucks, sorry for your experience...I've been there with a 3yo and infant (now a 5 and 2)!
I feel like I hijacked this thread with my monorail debacle. Sorry, everyone! But, it's like Disney therapy on these boards.

NedsTJ, my breakdown day was Weds the 14th.I made it from Epcot to the TTC. It was the resort monorail at TTC that broke down, so they told the mass (two monorails worth of people) to go to the ferry. We had waited a good 15 minutes at the TTC for them to declare the full train in front of us broken. I wish we had the foresight to see that the monorail was not leaving and just head back down to the ferry at a leisurely pace (and maybe I would have gotten a seat to feed my baby!), but we didn't. We waited hoping the monorail was going to go and then almost got run over by all the people RUNNING to the ferry when they told everyone to leave the monorail station.
Our plan was then to take the ferry from MK direct to Grand Floridian. When we got to the GF ferry, he told us we had to take our baby and toddler out and fold our double stroller. I get it, those are the rules (although I didn't know that at the time). At that point, after a full day of touring, I was so tired, and my kids were in such a TERRIBLE mood, I just couldn't stomach the thought of going through the hassle and I just give my husband a defeated look. We look up and thankfully the resort monorail was working again! So here we go again on the now working resort monorail, just starting from Magic Kingdom, saying hi to the TTC again, and then finally back around to the Grand Floridian!! Oy vey!
But now I have learned we could have just walked back to the GF. Hehe, such "newbies."
Also, it's very stressful when you are on the monorail and they tell you they have to shut it down and repower it. It just makes me nervous and a little bit claustrophobic.
All that being said, I just can't wait to plan our next trip! It was a wonderful time overall.
