This was recently pointed out by someone else on another batch mix thread, but I think the more critical issue is getting the proper dilution factor in pre-batched drinks. If I was in your shoes I would figure out whether or not I wanted to pour and shake the pre-batched drinks on demand or whether I preferred to let guests fend for themselves. If the former, I would just scale up the batch and keep the ratios just like you would for an individual drink, then for each imbiber I would pour one drink's worth of batched Mai Tai into a shaker with crushed ice, give it a hard shake and pour unstrained just like if you were mixing up individual cocktails. If you decide that will be too time-consuming and you'd rather just pour pre-batched drinks into cups with ice then you need to add an approprpptiate amount of water to the batched drink to approximate the dilution that a hard shake on crushed ice would have given you. I have seen 25-30% of the total volume of the cocktail as a suggested rule of thumb.
