It's usually almost always just me and DBF. We sometimes don't always agree on what we want to do and when, but we compromise. 4 out of 5 times we both get our ways since we have time.
On Sunday night we rode most of the Fantasyland rides and he always lets me pick what vehicle we get to ride (Sunday night was Teacups and Casey Jr) and I always ALWAYS pick the pink ones. So since I'm a nice girlfriend I let him pick what color Dumbo he wanted to ride and he picked blue.
We usually have the hardest time on what to eat. But we have that problem at home too.
I always like to do groups, but nobody either seems to get their act together or else they flake on us. Just one of those things, I guess.
I'm really envious of the big family groups like yours and Jazz's. We have a really small family (just me and my bro and hubby and his bro - no parents anymore) that doesn't have the same tastes or goals in a vacation. It's like pulling teeth to get everyone together for the sake of my kids and it's only happened once (and to Monterey, not DL or WDW). It would be nice to say "Let's go to WDW - rooms are taken care of due to DVC - and have a good time together for the sake of the kids!" and have everyone happily agree!
