I want to take my kids when we go. I read they have to be 8 and over 90 pounds. How strict are they on weight. My daughter is 11 and only weighs 60 pounds. My other daughter will be almost 9 and not quite 60 pounds. But since we are going tandem does it matter since I am way over 90? Don't want to get them excited if they won't let them go. I don't know too many 8 year olds that are 90 pounds.
