Importing full contact details into 2nd iCloud acct

Hi,

I am trying to export/import some contacts from my address book, with all of the contact fields, from my Contacts to another Macbook Pro that I own. However the 2 methods I have tried don't work;

1. vcard export and import

2. Have both iCloud accounts active in Contacts on the same mac and copy the contacts between one iCloud account to the other. (I also don't want to have both iCloud accounts normally shown on the other mac for a number of reasons)

With both methods, only limited contact information is exported - fields like Notes are missing.

Any suggestions on how to send full vCard details or copy between iCloud accounts ?

Thanks.
