My son will be having foot leg surgery in September and we are going to WDW for MNSSHP on Oct 5th. He will have an above the knee cast so he won't be able to walk. We can put him in a stroller with my 1 yr old but there's no way I can hold him while we wait in line....he's 40 pounds and those casts are heavy! Can I get an access card for our family if he is in a stroller or do we need to have him ina wheelchair (we'll have one at home but I'd rather not lug it with us and just do the double stroller instead. Any advice?? How do you get an access card??
