I think it's ok to limit what you serve, but I would definitely keep a beer option, red & white wine & try to have a vodka/rum option. As far as it being too early to drink...umm, last I checked, as long as it was 11:30 am - drinking happens! And, even though people have to go to work the next day, I don't think that will hinder the drinking for most ppl - it's a wedding! Just my opinion
