How long is Karen planning to travel?

M: When are you off to California, Karen?
W: I don’t know yet. Probably in August, for three weeks. I’m still looking for another woman to share the driving.
M: Are you going in that old camper van of yours?
W: Yes.
M: Well, good luck to you! I hope it doesn’t break down. What sort of person are you looking for?
W: Somebody about my age—in their mid-twenties. Somebody a bit like me.
M: You mean someone always on the move doing things.
W: No, I’m not like that on vacation. I’m quite laid-back. I enjoy a bit of swimming or cycling but what I really like is lying around on the beach watching the sun set.
M: So you want a travel companion with an easy-going approach to life. Someone to enjoy the sights with. Does she have to speak Spanish?
W: No, I speak pretty good Spanish. Don’t forget I used to live in Argentina.
M: So where are you going to find this other person?
W: I don’t know. I thought of either putting a small ad in this lifestyle magazine I buy or putting an ad on the noticeboard at the gym. What do you think?
M: I’m not sure really...
