going on holiday

so me and my partner planned to go o holiday the end of this year when its cooler as me and hot weather dont mix but we cant as it is too close to due date. What are peoples thoughts about going on a holiday after little one is born, who would stop with grandparents. is it wrong of me to what to.do that?? when would be best to go if it wasnt a bad idea ***edit - they'd be settled in a routine and sleeping through ***
