Well, looks like this is going to happen, but not the way I thought. After a little more "talking" to both Sarge and McWeedy, It's just going to be me and the weedwacker going.
Sarge is staying home.
That seems yucky, but it's not. Sarge is worried about missing work, and his girlfriend is having her birthday on the 3rd, and he's already taking several weeks to go on a long trip to Asia. On top of that he doesn't really like crowds, so the idea of Orlando on the 4th didn't really do it for him. I badgered him a bit, though, because wanted to make sure he knew that I wanted him to go, and that there wasn't some other reason he didn't want to go. But really, that's all it was.
McWeedy, on the other hand, finally said last night "I'd really like to stay at the Hard Rock and go see Blue Man Group". So I went ahead and booked the vacation for the two of us. Today, when I called him to tell him about the specifics, he was VERY EXCITED! Told his friends that "just me and my Dad were going to spend the 4th in Orlando.....". He was really stoked, which surprised me.
So in the end, I didn't get what I really wanted (both sons with me on a "guys" vacation), but I get to go see my favorite group, get to spend some quality time with my son, and Sarge gets a week of "alone time", which he seems to like (still wonder if he's a touch "aspie"). I'll make it up to him in other ways, though, and will still find a way to get him out (maybe use the money I'm saving from him for a rafting trip in Colorado?)
So, hopefully, it'll all work out. Now if I can just get through the next week while wife and Dancer are gone without finding some reason to bang on McWeedy, wife's "vacation" won't be so bad for the rest of us.
Wish me luck, everyone. And thanks for all the suggestions and advice.
