A plan works perfectly if you guys would be apart and this is a full blown trigger for her.
A plan can include the following:
1. set up a time you call and make sure you're on time no matter what!
2. video (skype,tango) so you can see each other and she can see where you're at.
3. make a plan on what you guys will do when you get back or before you leave. the one before you leave is very important that she feels safe enough that you can go on your own (if she can't come).
If she is coming with you,I doubt your work will have any issues if you pay for the extra of rooming another person. If your work is a pain, all you have to say is that at this time is the issue is personal and you would like some consideration. If they still won't let it be, set up a room in the same hotel for your wife, and go sleep over there with her. Tell the guy you're supposed to bunk with that you're letting him have the entire room as you're going to be next door with your wife.
More power to you.Love is a choice.
True love is harder to come by than soul mates. True love requires work.
Ignorance can be cured with knowledge. There is no cure for being an idiot.
