Don’t take large amounts of cash with you. Traveller’s cheques are safer. Credit cards are accepted at most big shops.

Maybe the biggest danger is from the pickpockets if you travel in the UK. It is a good idea to keep your traveller’s cheque, passport and your credit card in safe place. Other dangers include spending too much, eating too much, and of course, drinking too much whiskey in Scotland

The emergency telephone number to call the police, ambulance or fire alarm is the same — you dial “999”. If you dial “999”, you have to tell the operator your address, telephone number and what service you want.

You can find hotels in every town. The travel information services are very helpful and they offer free maps.
