Hi there Yulia,
I have looked into the issues you reported.
We do support basket bookings for multiple children, and you can now also book different children into either the same or different dates.
Just make sure to choose how many tickets you need by hitting the + icon on the ticket screen.
Two tickets = two children, unless they are group or family tickets.
Once you are happy with your ticket for the chosen session, you can add it to your basket and continue adding more dates and tickets if you like.
Regarding the timing out problem, I could not see any errors from your session in our records.
We would love to hear a few more details about your experience to better understand the issues you raised and ask you how you think we could be better.
If you have any time to jump on a call, or send some more information over via email, we would be more than happy to chat further about this.
Please let me know by replying directly to this email,
Kind regards,
Melissa from Pebble
