How do I register or sign in?
Use the same email verification-code form. No password is needed.
The header's Sign in / Register link opens the same account page. Once email verification is available, verifying an email for the first time creates a member account; subsequent verification signs you into that account. No separate password is needed.
Code availability depends on the service status shown on the account page. You can browse itineraries, tickets, stay themes and public Q&A without registering.
