So in MP it's easier to protect a couple of cities rather than one, or there is just no reason to have that much riding on one city?
I have always put my wonders in one city, MP and SP. It is in the middle of my territory and the best defended.
Mainly because I found that in MP if someone wants to take a city with a wonder, they are going to go for the one that hurts you the most (becasue you now have to fuction without the wonder, ie, happiness or troop support, etc) or the one that benefits them the best (Leo's, even if only held for a couple of well timed turns can upgrade your entire army) it is very hard to defend them all well all the time.
