Depending on the policy, travel insurance may be able to cover your non-refundable travel expenses. For example, if your tour is less than 30 days away and you become seriously ill - you will not be eligible for a refund from Panama Relocation Tours. However, some travel insurance policies may reimburse you for the cost of your tour.
Some credit card companies include travel / trip insurance as a benefit of using the card. Check with your credit card company to see if they offer this benefit.
We have limited experience with travel insurance companies and have never had to file a claim. For this reason we don't feel confident recommending one company over another.
