We're headed to DLR in October and have 5 day hopper passes. We are going to be in town for 8 days and wanted to at least add a day to our passes once we arrive. Has anyone been successful with this since they won't help me via phone?
In July we added a day to the 5 day park hopper, go to the ticket booth and you can upgrade the ticket there. Make sure everyone carries their ID as their name will be printed on the ticket. They might ask to see ID when entering the park, even if you have used the ticket for several days.
