RETROCON provides an online portal for creating an account, managing event purchases, and accessing tickets and related services. Visitors can register for a new account, sign in, review their purchases and tickets, update personal details and preferences, or request account cancellation. The site also directs users to frequently asked questions, ticket information, coupons, and terms.

The portal lists full-price and half-price admission options, with prices determined by the current sales batch and loaded from its ticketing system. Half-price eligibility includes students with valid identification, visitors aged 60 or older, and people who qualify under the stated disability documentation requirements. Visitors may also qualify for half-price admission by bringing one kilogram of non-perishable food for donation on an event day. The site explains that eligible visitors must present the required documents at entry; people with disabilities meeting the listed criteria may enter free of charge.

For the current edition, RETROCON requires users to create a new account, although they may reuse an email address from a previous edition.
