What would you do??

So 2011 is a massive year for this family and as we are hurtling towards it, I suppose I better get some decisions made and plans actioned. Hubbie turns the big 4.0. in July and in September we celebrate 10 years of marriage, and to be fair it is for better or worse and for richer or poorer. My significant other has been wanting to show me Las Vegas from the moment he got back, just before we got together those many moons ago. So i thought this coming year would be the time to do Vegas and do it in style. I've been imagining wedding vows being renewed with Elvis present, getting to see Celine Dion live and maybe catching the tiger guys. The thing is, what about the kids...? I live and breath my children, I never go out and any event the family does it does it all together. I can't imagine leaving them behind....but then again once in a lifetime holiday just the two of us sounds good too (we never got a honeymoon). I can't book until I decide whether they are coming with us or not and I really can't decide. Hubbie is of the opinion that on our own would be good but doesn't mind the kids coming. It would save loads of money with just the two of us but I know that my missing and worrying about them would ruin my holiday anyway. I am so confused and I can see me not doing anything therefore not having to make the decision. It is a big year but do I really want to celebrate it without the reasons I get up in the morning? Or should I just bite the bullet and let my hair down for a week and enjoy being a consenting adult. What would you do.....???
