Traveling before and soonn after pregnancy?

Hello all, I am 24 weeks and 4 days pregnant. I really want to do something this summer. I am not due until the end of september and I really want to take a vacation. Me and my husband been researching cruises and most of them require u to be 24 weeks or less. I am about to be 25 weeks. I am not high risk so I was wondering if i could just go on a cruise anyways. My husband prefer to wait until the baby is born but once its born i dont think i can leave my newborn for 5 days. I know its stupid of me to worry about a vacation right now but I have a 3 year old, I just finish school, and i bust my azz everyday at work dealing with woman, their hair,baby daddy drama etc(i am a cosmetologist) so momma needs a break. If we wait until the baby is born, what age would u feel comfortable letting the baby stay with the grannies. PS I am going to feed.
