• Infants under 1 year old enjoy free admission and free access to infant play facilities. Children aged 1 to 2 (under 3 years old) also receive free admission; however, a separate fee will be charged for the use of toddler play facilities. Age is determined by the date of birth on the passenger's passport.• This product is already a discounted ticket, so no separate child tickets are provided; children under 3 can enter for free with a passport.• The ticket includes a Lotte World 1-Day Pass, allowing unlimited access to most attractions; however, a few attractions require additional fees—please refer to the official Lotte World announcements.• For the “1-Day Pass + Aquarium” option, aquarium tickets must be redeemed together with the Lotte World ticket.• The “1-Day Pass + School Uniform Experience” option provides a basic uniform set (jacket not included, can be rented on-site for an additional fee). Electronic tickets are not accepted for this option; physical tickets must be collected at the group ticket counter before use.
