I've been through here at least 3 times. Shown here is a church in the capital city of Vaduz . For all practical purposes, Leichtenstein is just another part of Switzerland. It has treaties tying it closely to Switzerland. There are no border checks between Switzerland and Leichtenstein.
Swiss money is used.
Lots of tourists do come here, you'll see many on the streets of Vaduz. Come here if you must, send some postcards with Leichtenstein stamps, eat lunch, then continue on.
