We would fly out when Craig's parents leave in early May. I would stay until the end of the month and then fly directly to Detroit for my con in early June. Then, I'd fly home to California. The kids would stay in the UK with Craig and his parents until Craig returned around the 4th of July.
There are huge advantages to this. It cuts down on costs for the company because Craig and the kids would stay with his parents. They have room for the kids easily,and since Craig will be working most of the time anyway, he has no problems sleeping on the couch for the duration. It also means only renting a single car, since they don't have to worry about providing me with transportation.
The disadvantage to this, of course, is that I don't see Craig or my kids at all for about 6 weeks. And considering I leave for Toronto on the 11th for a week, that's much closer to 7-8. I would be pretty much on my own for that entire time, with very little live contact beyond what I get online. There's always the option of going back to the UK after Detroit, and turning around to bring the kids back with me then, but Craig's not keen on that.
I think my question is, could you do it? I'm still trying to decide if I can or not.
