Keeping travel documents such as passports and covid related documentation safe whilst travelling is a concern for most holidaymakers but there are ways of making sure that your paper documents are secure whilst still being easily accessible.
A plastic A5 size zip close wallet is a really good way to keep the documents in one place. Covid test results, passports, holiday confirmations and insurance documents can all be kept together but they are accessible when you are required to show them on your journey. The advantage with using an A5 sized wallet is that it should fit easily into a handbag or a pocket in your hand luggage. Additional documents such as boarding passes can be put in the plastic wallet when they are issued ensuring that they too are kept safe.
Once you are at your holiday resort your documents should be kept in a secure place such as a safe. Some hotels retain your passport for the duration of the holiday, but you may need it on your person if you are travelling over borders to neighbouring countries during your stay. As the UK is now no longer in the EU different rules may apply so it is best to check before you travel.
