I think so. Magic pass is sold separately once you are inside so.

whole day

Hi. There will be something for the toddlers but do note that most rides there's height restriction eg 110cm or 120 cm abv. My kids are 5&8. We noticed some rides eg kiddy bumper cars there's a fee stated of krw3k for kids with below 3 without a purchased tickets. U might want to check on the website on what are the rides suitable for below 3yrs. Cos although their entrance is free, the adult tickets still cost krw30k+ online. There's 50% disc for foreigner in sept during chuseok period. Do chk out their website.

We just used a site to buy tickets, voyagin. It was easy and simple and actually did this while waiting in line at the South Gate to collect our tickets. The tickets ended up being 34000 won per person instead of the 57000 won per person. Hope that helps. I would advise to go early as possible. Be there for 9:30 as soon as door opens so you can go on the rides with less cueing. As we found as the day progressed the lines got much longer and this was on a Monday.
