If you make reservations to stay at one of three hotels in the Disneyland Resort during the first three weeks after the new Star Wars land opens, the park will automatically send you reservations to visit Galaxy's Edge for a four-hour period. The free reservations through the Disney website, which went quickly, still require paid admission to the park. Each reservation can be used for a party of up to six people, and each adult in the group must show government-issued identification.
