Thanks, everyone for your nice wishes and suggestions! Thanks esp. somegroovychick—sounds like you had a really interesting mix at your wedding.
Hunnie, your ideas are great but I have to say in our case a first dance is definitely out of the question–my future Abu-ji would have a heart attack! 
We will have some music playing on the yacht though, so who knows, maybe some of the cousins will have a wild moment. I’m not going to hold my breath, though! 
When I was planning everything I thought it sounded like fun but I’m just worried about my fiance’s family feeling comfortable! I know this will be very different for them.
