arundel cruiser

We go to Copenhagen, Warnemunde, Tallinn, St Petersburgh, Helsinki, Stockholm.

We have excursions booked for the 2 days in St Petersburg.

We are booked on a Baltic cruise in July on CMB Magellan. Did Canaries in the Spring and had a wonderful time.

We have booked a couple of excursions but generally do our own thing.

Our big question with this cruise is - what currency/s do we need. We seem to be going to a lot of counties with different currencies. Can anyone give us any clarity as to what we need or don't need? We aren't big spenders. We don't buy souvenirs or meals while we're ashore. We will almost certainly use public transport and maybe buy a coffee.

We don't want to end up with little bits of random currency. Has anyone done this and got any tips.
