Who would you want to have access to?

For the sake of argument, there is a fairy of access that will grant you access to three people (they have to be living, no conjuring up the dead), the 1st person you are granted access to, it is for an indefinite time, the 2nd person access will be for 18 months, and the 3rd person access will be for only two weeks. Access in this case is that you can reach them by phone, email, chat, Skype, etc. they may not do ask you may ask of them, but they will receive your correspondence or calls. Who would you want access to and which level of access would you seek to have with them?
