We were there Saturday from 8:30 to about 6:00, and the crowd was staggering but it did not feel like the most crowded I've seen it. Sure, the lines were long, but we weren't riding coasters. The only really long line was for LROTO, but only the youngest wanted to ride, so the rest of us sat and people watched for 45 minutes. We hit the train station just before a train came in, and we didn't make the next one, but we did get the second one--we've waited longer during OTC when they were running two trains. (Side Note: we rode behind #43 for the first time this year, all our previous trips having been behind #13.) We got off the train and went right to FM, and the end of that line was on the bridge, but it moved quickly. (The music was turned up really load: we could hear it well for the first time this year.) Again, the line wasn't onerous.
I think part of this was that there were really at least TWO crowds there Saturday: when we left, as many people were coming in as leaving. There seemed to be an early crowd and a late one, so, depsite the high numbers, not all of them were there the whole time.
