If you are planning on booking your holiday for next year make sure that if you are booking through a company that they are ATOL protected. If the company goes bust then you are covered if they have an ATOL licence.
You could have problems if you book flights and accommodation and transfers yourself from different companies online. Whilst on holiday if the airline goes bust you could be stuck there and have to pay your own way home.
If booking through a company ask for their ATOL number and pay by credit card for that extra piece of mind. If in doubt, check on the ATOL website at www.atol.org.uk.
