I miss the old lap bars/seatbelt. I usually asked for that middle seatbelt and made sure it was plenty loose so I could get air time.
One time my sister and I went (without children!) and rode ToT (well, we rode it 13 times that trip...) and we were seated in a row with a lap bar. The man next to my sister was rather large and while we were lowering the bar my sister turned to him and said "suck it in". I couldn't believe that she said that to a perfect stranger, but his wife thought that was so funny.
Of course we wanted air time so I don't know why she was telling him that.
When we went last visit I had my 4yo with me. We did ToT 5 times (my little guy is very brave!) and I thought that the seatbelts were more secure when little people are riding in the same row as bigger people. The problem for people who like airtime, though, is that the seatbelts tighten up on their own so it's hard to make sure there is some slack.
It's a wonderful ride, though (my favorite from any theme park, anywhere), and my sister has a dream that we'll retire and work there. LOL She's retired now, but I have a very long time before I am. She also has visions of bribing one of the CMs there on a slow day and begging them to let us ride again and again without having to go through the queue each time. Now that sounds great!
