I'm jealous, vax! Those are the same flights I took in Oct/Nov.
This will be a great and eye opening time for the kids. They might even thank you one day.
Take face masks for the flights...those throwaway paper things dentists wear...so that you don't have to spend two weeks in bed for all the wrong reasons, and get better just in time for the flight home.
Give Keithie, L and Jam a squeeze the stuffing out hug for us. No RMortis this time?
