I;m trying to reserve four seats (max it does is only four because I really want 5) for the Sapsan from St Pet to Moscow. I enter all four people's information and click on the seat range that I want, and when I click RESERVE PLACES it then tells me:
INVALID REQUEST PARAMETERS. PLEASE CHANGE YOUR REQUIREMENTS.
