I read this thread and I had one of those 'I can laugh about it now' moments...
6 plus years ago... as I was planning the long-awaited first family trip to WDW, I put down my WDW planning guide, dog-eared as it was, and asked my then husband to pick a hotel. I wasn't nearly so planning-obsessive then (just one planner book, not the half dozen that grace my nightstand today) but I knew if I didn't plan it no one would. After a brief read, I told him to pick one of the monorail resorts. I was torn between the CR and the Poly, but I made it clear I would be happy with either, and I would love it if he made the final decision so I could book a room. He shrugged to indicate it made no difference. I asked if he would be okay with whatever my decision was. Again, he shrugged. I persisted, asking why he wouldn't pick one. He reluctantly stammered that he didn't know if he would be around at trip time. He needed to find himself. He thought he might be somewhat commitment-phobic (after 11 years of marriage, no less.) Blah blah blah. I don't have to tell you what happened, and I don't have to tell you her name.
We spent the trip money on a divorce. No concierge service. No free upgrade. I went back to what I was doing before I became a mother. I packed the guidebooks away in moving boxes. Disney would have to wait.
That spring seems a million miles away, but I can recall that afternoon as if it were yesterday. My kids and I have grown in so many ways since then. They've tagged along as I traveled all over the country and europe for work. They made an extra spot at the homework table for me when I went back to finish my degree. They never let me forget why they are the most important things in the world to me. But beyond all that...none of us stopped dreaming of going to WDW, and this October we get our chance.
Anyhow... your comment about your spouse not sharing your enthusiam for Disney reminded me of that moment in my life. Not one of the best, as far as moments go... but it was pivotal, and I thank you for letting me remember it here.
Enjoy your trip with your son. They are only 6 for about 20 minutes, and before you know it you'll be visiting prospective colleges with him. PI will always be there...
