You generally cannot take a purse with you onto a high-intensity roller coaster for safety reasons; loose items can become dangerous projectiles during drops and inversions. Most major theme parks (like Universal, SeaWorld, or Cedar Point) provide rentable or free-use lockers located right at the attraction's entrance where you must store all bags before entering the queue. On "family-style" coasters or slower rides (like many at Disney), you may be allowed to place your purse on the floor of the ride vehicle between your feet, or the ride may have a small "net" pocket in the seatback. For those who want to keep valuables close without a locker, the best strategy is to wear a fanny pack (waist bag) with a secure buckle, as many ride restraints (like lap bars) can comfortably close over them, and some parks specifically allow them while banning purses. If you have a small crossbody bag, you may be asked to store it even if you try to wear it under your shirt. Always look for the "Loose Item" signage at the ride entrance to avoid being turned away by the ride operator at the boarding platform.
