Ah, be careful there! 8<)
Remember, it is her wedding, not yours! (Yes, take the trip - though you "do" have all the reasons and right to be concerned with the planning and preps. )
Tell her - Heck, tell him too! - that you trust them and trust them to do just fine. Then go to HI and be the good mommy we know you are and worry. 8<)
That, or send them to HI and let you do all the worrying in peace without her to distract you.
She is beyond efficient and i have no doubts whose wedding this is. i DO know who is paying for it though, robt, so to that extent i get a say-so on some things. She is cost-conscious and conservative, but it is going to cost a small fortune. They are going to Italy on their honeymoon, so they won’t miss Maui too much. i am inclined to go, and i feel perfectly calm, but i have had several friends go through marrying off their kids within the past few months, and i know there are stresses that will come. The other factor is he has another conference in October in England and i am pressing for that one, instead, so we will see.
