we had 9 people (only 8 had the bubbly, i dont like champagne!), and the one bottle was enough for 8 people with glasses about two thirds full. just dont order soda, bring your own, they try to charge you about $3 each!!!
and the cake is huge!! everyone ended up with cake every day for the next week, and we still ended up giving the top layer to the staff at POR!!!!
