Vacation

So I'm leaving to go to Mexico my baby will be 10 months old and this would be the first time I am leaving her for longer than a night we will be gone 7 days what are your thoughts on babysitter should I have someone stay at our house with her the whole 7 days or trust grandparents to pack milk and everything she needs to go from house to house because just one grandparent isn't able to watch her the whole time
