What I am about to say is not in any way to be taken as an attack on DH, just an obsevation from someone who has been with a daughter... Here it goes...
If hubby is Ok with not going and you've got family with you - go for it!!! Unfortunately, I think he will regret this more than he realizes because for years to come one of your girls will say "You remember when we...." and he won't be able to nod and smile. We went in June 2004 when my DD was 4 and she still talks about it, almost weekly. The magic is just great.
Like I said, I don't mean anything negative, just something to think about.
