I would really like to visit Cuba before it changes too much. We are a family of 4, kids will be 10 and 13. Ideally we would like to be in accommodation that will allow them to make friends with other kids and enjoy activities, but we would also like to take day excursions and see a bit of Cuba. We could go at Easter or August. Budget something like 6K for around 12 nights. Do you have any advice, recommendations?
