Being overweight on Universal Studios & IOA Rides.?

Wondering if a person weighing "330lbs" with a 52' waist @ 6'2' could hop on most of the rides in FL (Universal Studios/Islands of Adventure/Busch Gardens/SeaWorld). Does being overweight hurt your experience at FL Theme Parks? My family & I are leaving in a week for FL. Info & experiences would be helpful. & if your in the same situation. What rides were you able to ride? Thanks
