5. Be realistic
Every air-conditioned building from the cinema to supermarket will be on your radar and if you're lucky enough to enjoy a final break away before becoming a family, think carefully about what destinations you can cope with. Exercise is still important, so opt for swimming to keep active, but refreshed. Remember that extreme temperature drops are not safe so steer clear of hot tubs or plunging into an icy paddling pools, no matter how tempting they seem.
