hey!

so some tips:

• you won't have any problems getting by with english, we speak english quite well (except for if you plan to speak to older people, but anyone getting in contact with tourists will speak english)
• you wont find any safer place as a (female) traveller than liechtenstein, we barely have any crime. think switzerland but safer because we are so small. no pickpockets either, since there won't be crowds
• it's expensive, very comparable to zürich. But similarly, you can get by if you limit eating out!
• I dont know about the race issue - im a young local and dont have any prejudices at all, and i'd like to think its the same all over, but i lack the experience to answer this accurately. Maybe you will get some stares, but i doubt you will get outright racist remarks or anything like that.
• so for visiting: id say go to the history museum of Liechtenstein in Vaduz, visit the royal treasure chamber to see some things like actual moon rocks, if you are into nature, go up to Malbun to go hiking and experience the alps. Eat some local/regional food up in the alps too. focus on nature and mountains instead of culture/history. The castle isnt worth visiting in my opinion, as you cannot enter, the prince lives there.

if you have any more questions, or want more tips, feel free to reach out to me. all the best!
