What's your opinion on a yacht wedding?

My dad and step-mom did a yacht wedding. It was lovely. It was in late April in Southern California, though, and pretty small (immediate friends and family - 2nd wedding for both of them). As many have mentioned, all inclusive with catering, drinks, etc. They sailed it in the harbor itself (max speed limit of 5mph), so it didn't really rock enough to cause seasickness.

Well, I get seasick so...

Looked into it, visited a few. It will be outrageously expensive unless you're having less than 75 people. The catering is at least $80 pp unless you bring in a caterer, which can also be pricey. And they're much smaller than you would expect
