Looked through a few portals yesterday and opened Captain Cooks just to see what the setup looks like. The form asks for common contact details and some personal fields. Honestly, the landing screen felt a bit clunky at first glance, but nothing really critical. For those who want to check the details directly,
https://captaincooks-online.com/registration/ shows their main technical steps and account fields. They mention data protection standards, identity checks, and common safety protocols on desktop and mobile. In the end, just another ordinary portal, so everyone should check it and decide for themselves.
