Cedar point w/ big thighs?

I'm about 275-280 pnds and I'm going to edar point, I can fit into a large in shirts at stores like american eagle but my waist is small, my hips and thighs and but carry most the weight...... I wear a size 20_22 in pants. Should I even bother going? If I can't fit into all the rides I don't wanna even go..
