How do I make a reservation with a third party ticket that doesn't have a barcode? I am getting an error message when entering the number I was given.

If you selected a date while purchasing your ticket from either us or a 3rd party then the ticket is already reserved for that day.

Did you select a date when you bought it through the third party?

Call, and I wouldn't buy or acquire tickets that way unless they are complete.

Guest services should help upon arrival

Legoland membership services will fix that upon entering park

I did. It is giving me an invalid ticket error

Go online and pick the option for a third party buy
