I did two double batches for my wedding (April 26th): a lightly dry-hopped APA and a basic American Wheat. As the guest list got bigger, I decided to bring the rest of my brewed goodies to back them up - about 30 bottles each of IIPA, Deception Cream Stout, and JAOM (mead). Should have labeled them, though - the IIPAs were taken early (because they were in delabeled cobalt 1664 bottles, the prettiest brews on the table), then left on the tables with one or two sips taken from each because a bunch of Chinese mothers from our kindergarten - the kind of people who think a Tsingtao in the single-digits for IBUs is too bitter.
Both of those brews came out well and carbed up in time for the wedding; I started brewing for the wedding about three months in advance, and probably could have gotten a third double batch done and conditioned in that time without needing any more fermenter space. If I were to do it again, I would do the APA last - the hop aroma faded quite a bit in the extra month and a half of bottle conditioning.
If you start brewing now, you've definitely got time for two brews per fermenter, even if you're bottle-conditioning. If you want something hoppy, though, wait a few weeks for brewday. You could brew an IPA, ferment for a couple weeks, do one or two dry hop sessions in the primary fermenter during the third week, then bottle and condition for another three weeks before the wedding. By that schedule, mid-June would be a good time to brew, in which case you could do one brew in the next week or so (APA, wheat, cream ale, whatever your guests would enjoy), then start the IPA right after bottling this first brew.
