Hi Art and Kim ...
I don't know if you've already been down, but I thought I'd try to help with this one. I am a very similar size and have ridden Kracken at least 4 times. that being said ... they have very specific rows with one seat (about the third one in) that will accomodate a bigger size. Even then it took a little help to get the belt attached (the cast member was very kind ... reffering to the "football player" seat). I was a bit squished but it was still fun. They have seats at the beginning of the queue to try but I felt funny and didn't do it.
Anyway, if you haven't gone yet ... have fun!
Dave
