It sounds like while your husband had a good time, he didn't have such a great time that he finds value in going again so soon at the same price point. Like many things mentioned on this board (you need to eat at CRT ONCE, you need to try a Halloween/Christmas party ONCE, etc), it sounds like he needed to experience this trip ONCE and then try new things/use money for other things. He'd go back if it was uber-cheap (or free, b/c who turns down free), but he didn't love it enough that he needs to go back soonish...
As for looking at things to spend money on, that's human nature. If he hasn't mentioned them to you, I doubt he's looking to pull the trigger on a boat or golf cart or 4 wheeler soon or without talking to you 1st. I look around at all different vacation sites even though I know I won't be booking any of them for 12 months, since I have this year's vacation plan set...doesn't mean I don't keep up with happenings in Orlando, Pigeon Forge, DC, Boston, Columbus, and Charleston (and cruises - who can forget those, since that's this year's trip

)...
