Many older travellers enjoy home exchange holidays for a number of reasons - the convenience of having a real home base, the cost savings (especially when retired and able to take longer holidays), to be near grown children who have moved far from home, and to continue to explore new places in comfort.
One problem that seems inevitable as you grow older is in finding suitable, affordable travel insurance, especially if you have a medical condition.
A number of companies specialise in insurance for older travellers. If you live in the UK, check out the following:
Saga: no upper age limit and covers most pre-existing medical conditions using a medical screening service.
Able2travel: travel insurance for those with pre-existing medical conditions up to age 79.
Intune: Part of the charity Age UK (no upper age limits).
Free Spirit: specialises in travel insurance for people with a pre-existing medical condition (no upper age limit).
Medici travel: up to age 99 with pre-existing medical conditions.
