c) I like my princesses to be spies, while maintaining their mobility around the campaign map so that I can bring them home and marry them to a General of mine if the need arises. I just feel more comfortable using my daughters as loyalty boosters than alliance makers.
Ditto that. Ever since that campaign I mentioned (in which I lost provinces to other factions when I plunged into civil war), I almost never allow my princesses to marry into other factions, instead hitching them to good generals/governors who are of only so-so loyalty. I'll only marry them into another faction if:

1.) I really really *really* want an alliance with them
2.) I want to help keep that faction alive (they're a usefull ally/buffer state/etc.)
3.) I have a princess to spare (i.e., I don't need her to marry one of my generals)
