I quite agree!

It's why I came up with the Hampshire-class yacht for my Second Scions' Society adventure.

Forget the piddling little yachts you've seen, think more Downtown Abbey in space!  This could carry an owner and family plus 12 guests (with partner + 2 servants apiece) with room for 100 servants. 

I really ought to get this published... I just can't help feeling it would be better with Part III which I've not written yet.
