We have Super Grover Passes. One of the listed benefits of pass holders is a discounted admission for guests at the other parks. At this time we just have our print at home vouchers. I am unable to log in with the voucher. Does anyone know how much of a discount we are able to get for our friends? I tried calling but unfortunately they were unable to tell me. We won't be going until the end of April and if it is not a good discount we may be able to get something better online. Friends will be going most likely for just one day with us.
