Okay so, this is fairly embarrassing but DP has suggested we go to Alton Towers/Thorpe park or something along those lines in the next couple of weeks.. And now I can't stop having nightmares about not being able to fit on the rides (I am 18st and a size 20-22, I know I need to do something about it) but DP says IABU for being so worried.. So AIBU or will I really not be able to fit in the rides
