I'm in France through late June. I will probably do at least the ACP 200K in the spring, on March 31. If that goes well I might give a 300K a try, too.

I've never actually done an organized brevet, though I have done solo, unsupported rides of up to 200K within the time limit. I registered for a 200K once but I had to pull out of it due to an ignominious injury: hurt my knee getting out of bed two days before the brevet!

I'm also considering doing a couple of the Flèches de France: definitely Dieppe, which is only 184K from Paris via the touristic route (171K via the classic route), and maybe a 300K-ish one like Calais or Mont St. Michel. France is a great country to cycle in, though after a while it gets tiresome riding out of Paris and back in.
