Crazy Magical Express Question

[minniesmom]

I have a crazy situation that I need help with. My DH, myself, DD and DS will be traveling to Orlando in Oct for the cruise. We are coming early and going to Disney for two days before and staying at POP. We had planned on using ME. However, things have changed and I will already be in Orlando prior to our trip so I will not be using ME. My dad is flying down with my DH and kids and going to MNSSHP with us but he is staying with relatives. So my question is how to get him to Disney. Can he use my seat on ME with my family? Does anyone have any suggestions?

Thanks!
