Thank you to those of you who offered some helpful advice.
If you've never worked a nightshift before or had a family member that did, it's hard to appreciate just wanting to sleep, whether it's Xmas or not! I used to work nights, and DH has done shiftwork as long as we've been married, so I know what works for us. If he is off, he comes along with us, but of there are holidays when the kids are off school and he is working, we've gone out of town without him, so it's not like this is something new for us. It works for our family, and he has never had an issue with it, so I know that's not the deal now.
So back to the original issue about leaving the country...I think I'll suggest the passport to him. At least he would be able to get to the Bahamas quickly if he needed to.
Thanks again for the help
