Hi My husband has booked a two week cruise in the Mediterranean for the two of us along with two other couples. My diabetic son is 16 and would be staying with his sisters who are 19 and 22. I know each child is different but am wondering if anyone has experience in this area. I am very nervous about the idea and want to cancel. My husband does not. We would have cell phone reception most of the time. I am worried about things like not being able to test him in the night if he has been exercising or even (it has happened a couple of times) drinking some alcohol. Clearly rules would be set and many instructions and emergency contacts would be left. His sisters are quite vigilant on the social front but not knowledgeable enough about diabetes to handle the medical side. Any thoughts?
