My family is going to Disney next month. I have never been (my dh has years ago) and neither have my children. I am overweight (size 24) and am wondering about larger people riding the rides. I would like to be able to ride some rides with my daughter. I am concerned about the seat sizes as well as any bars that might come across you (lock into place) to secure you in the seat. Any information will be helpful. Thank you so much!
