My husband and I don’t drink alcohol so always get the soda package. The freestyle machine also has lemonade and Powerade, basically every Coke product and flavor imaginable. If your son won’t be drinking a lot of soda, maybe he could share with his siblings. I’m not saying filling the cup and dumping into another container for each kid, that’s dishonest, but if he is only going to drink a cup or two of soda all day, I think it would be ok to also get a mug of lemonade or Powerade too. My husband and I run and workout every day and in order to stay hydrated from that and being in the sun, we drink continuously all day long. We also get a refill before heading to our stateroom for the night so I’m sure we drink more than most people. Just a thought.
