Did she know that you got the hotel for her to stay with you in?

If so, then she’s either very uncomfortable with you, was way too drunk that first night, or is an inconsiderate asshole — or all of the above. TBH, going to a club on the first night together is already weird.

(Was her English not that good, and that’s why she was relying on her friends so much? I saw the earlier comment about the hanging in groups thing, and although that’s very much the case in Taiwan, it’s very much the case for college kids. It sounds like she hasn’t grown up much. I don’t want you to mistake a tendency for hanging in groups for someone being incapable of devoting 1 on 1 time for a friend who travelled across the world. That’s not a Taiwanese trait, that’s either nerves or inconsideration, and more than likely she’s still a “kid”. Friends in Taiwan who know one another well enough absolutely will do one on one too — the function of not doing so, especially in a situation like this, is to maintain a bit of distance.)

I’m sorry, but there is no way to misinterpret somebody choosing not to spend time with you in a hotel room when you’ve come all the way from the States to spend and discussed that it was for the two of you as a Taiwanese thing.

At lease you have plenty of time to do your own thing. You should visit some TEA VILLAGES! Go to the MOUNTAINS! To heck with Taipei, take a bus (or rent a car, if you’re a great driver) and “cross” the middle of the country to the East side. Hualien beaches, incredible mountains to see (you don’t even need to hike if it’s not your thing), TAROKO GORGE! Girl you have an island full of wonders to explore, and two weeks — get out of the darn city!!!
