Clarissa’s Review
I’ve visited the Studio Tour several times, but I haven’t attended NOX yet. The late-night setting is the part that stands out most to me. If I attend, this guide will stay practical and I’ll link to a separate review covering atmosphere, queues, food and drink, interactions and whether the premium ticket price feels worth it.
