Bank Account

I hope you all are having a wonderful day!  I just have a question, me and my husband have a joint bank account and for that reason we decided that we won't get a power of attorney, which now i realize as a big mistake. He signed up for "Navy bank". Now I am worried that I won't have any access to his money and I won't be able to afford the trip to GL for his PIR.. What do you suggest we do?

Can he wire me money while he is in BC?

I guess i could drive to Great Lakes all the way from San Francisco and just sleep in my car just to be able to attend PIR.

Please help!
