The currency in Lloret de Mar is the Euro. While you can take out Euros at any Bureau de Change, bank or even at ATMs, it will cost you and you’re not guaranteed to get the best exchange rates.
You may also find you end up paying some high commission fees on top, which can really eat into your holiday funds.
Most restaurants, hotels and stores will accept credit card payments (especially Visa and MasterCard), but if you want to go shopping in markets or stop off for a coffee at a small café then you’ll need some cash. It’s not mandatory to tip in Lloret de Mar, but it is appreciated, so keep some low-denomination notes to tip hotel staff, taxi drivers, and restaurant staff. Before you tip in restaurants, though, check your bill to see if a service charge has already been included.
