We have lawn seats, can I switch them for covered seats and pay the difference?

No switching of LAWN SEATS, for better seating; just pack A HAT suncreen/bug spray, Water, chair, blanket & a PONCHO. Summer Weather Safety Warning: Avoid Injuries by wearing comfy, rinsable, great traction SHOES, A HAT, long thin pants/skirt & short sleeve shirt. Hydrate, without alchohol, due to its side affects; dehydrates, impairs judgement, slows reaction & coordination. Drink Responsibly & please BE MINDFUL OF THE CHILDREN & OUR ELDERS. Watch your conduct! Lbvs

Call the Mann if you did it online they might be able to upgrade

Not sure how that works. I believe you would have to purchase all new seats. Call the box office.

I think you have to buy new tickets. And try to sell original.
