Watch out for bicycles. Danish cities have separate cycle tracks between the pavement and the road, and they are busy. Look both ways before you step onto one, and never stand or walk in it. If you rent a bike, keep to the right and signal with your hand before you turn or stop.
Vasa Museum, The Royal Palace, Drottningholm Palace
Money

Good to know
Bring a card, not cash. Sweden is one of the most cashless countries in the world: most people pay by card or with the mobile app Swish, and quite a few shops, cafés and restaurants do not accept cash at all. A contactless bank card works almost everywhere.

Euros and modest tips. Latvia has used the euro since 1 January 2014, so old prices in lats are long out of date. Tipping is modest: rounding up or leaving about 5 to 10% is enough, and it is not required. Check the bill, as a few places add a service charge.

Euros, and old litas at the bank. Lithuania has used the euro since 1 January 2015. If you find old litas notes at home, the Bank of Lithuania still exchanges them free of charge at a fixed rate of 3.4528 litas to 1 euro. City buses and trolleybuses no longer take cash, so pay with a travel card or by tapping your bank card.
