My husband has been in Iraq since September, and me and my two daughters are going BECAUSE of the deployment so we can have ourselves a happy time. If you're up to it, then I think it's would be a WONDERFUL bonding experience for you and your 2 kids. My daughters are 6 and almost 2, and while it may limit us on the rides we go on, it will be such a pleasure to get that one-on-one quality time with them and let them lead the way through Disney World. (A tip: one day I'm using the Mother's Helper service offered by Kids Nite Out, and this individual will escort me around and watch over my little one while me and my older daughter ride Splash and Space Mountain. I had to figure out a lot of things such as this, but it's been a fun discovery, and our vacation looks like it's only going to have 1 thing missing: Daddy. Everything else is a GO!)
Good luck with the separation, and if you need any help, I'm here for you! The deployment scared me and had me ready to give up everything just to have my husband by my side. But, here I am as happy as can be by the grace of God, and there's so much I'm thankful for. Message me if you wanna talk.
