Cheap travel insurance isn’t always the best solution – sure it’s fine if nothing goes wrong, but the last time you want to find out about shoddy cover is when you’re sick in a foreign land! That said there are a few cheaper places that I have found ok in the past: http://www.travelcover.co.uk and http://www.insuremore.co.uk to name but too – I’d still be wary though and make sure you read what’s covered VERY carefully… Don't let it ruin Thailand's beauty for you!

There are many insurance provider in Thailand. I with the family (2 adults, 2 kids) usually we use tour agency "Travel Insurance Quotes". We quite accept quality of service and the price. Do not find this message advertising.
