Nope, we just got back from WDW last week, and although our 24th isn't until December, we wore anni. buttons the whole time 'cause we're not gonna' be able to get there for our actual anni. either. We had a blast with them bein' congratulated all over the place and were even given a champagne toast at Whispering Canyon at WL one night at dinner in front of the whole restaurant! Our waitress had us give each other a big smooch, too!
Go for it, and have a BLAST, as well!
