[Manardariel]

Arwen- for simple reasons
1)She´s a girl. She-unlike Aragorn- would understand the need of having a rest from time to time. Or, as a matter of fact, washing my hair.
2)She´d show me Rivendell. And Lorien. Have always wanted to see that. Also, would probaby have very good chance of meeting Galadriel, as being her granddaughter´s friend.
3)She could teach me elvish
4)I suppose she would be a really nice to hang out with. Maybe I could even show her some nice stuff from our world- Loreal, the Peanuts etc.
5)Maybe Aragorn would come with us from time to time, and that would certainly be nice
