What does it mean if a girl agrees to go travelling with me for 4-5 days?

There was a thread on here recently where a girl was asked by a male friend to go on a long drive, and she asked whether he would see that as a date. There was no suggestion that he was interested in her beyond their friendship, and she wasn't interested in him beyond that either but thought it would be awkward if it turned out he did think it was a date. Turns out, despite not mentioning it at all, he did think it was a date. And things were awkward.
So, that being the case, the obvious question is whether you have given any signs at all to this girl that you are interested in her romantically, that you may be thinking along those lines, or that this trip may be something more than two friends sharing time. Because if you haven't, no, her deciding to go with you in and of itself does not mean romantic interest. It means she likes spending time with you sufficiently that she wants to got travelling with you. If you think it might mean more than that, or want it to, you need to ask her.

Genuine question from an asexual female - do men ever want to just hang out without hoping that you will sleep with them, even if you have told them you are not interested in them romantically?

What was your reason for asking her? She's got to have shown interest in being a friend or girlfriend for you hoping she'd make that kind of commitment.

My purpose was to find a good place to travel together, and to concede my feelings to her during the trip when atmosphere is good. Also, I wanted to know (to some extent) her feelings to me, because if she refused, then most likely, romantic interest doesn't exist.
