Traveling while Pumping

Hi mamas!

FTM here due 12/26 and I plan on EBF LO as long as everything goes well. So here’s the deal....my husband and I had a cruise planned and paid for before we got pregnant. The cruise is in April 2019 and we currently live TX (relocated 5 months ago) and will be porting out of FL where we’re originally from. My in-laws will be watching LO in FL and the cruise is for 7 days 6 nights. How am I supposed to store and get 7 days worth of breast milk to them and how will I pump and store breast milk while on the cruise? Has anyone done this before?
