i am really glad to see that they are including mugs in all of the plans. we pay for new ones every year. in the mornings we fill them up with coffee or tea to drink with breakfast. then we fill them up with ice water to bring to the parks, avoiding paying for bottled water. the mugs kept the water cold for hours so we love using them.
at lunchtime (whether counter service or sit down) if there was pop or juice left that we didnt drink with our meal, we would pour that into our mugs. we also went to the counter service places and got free icewater to pour in our mugs.
then back from the parks we would fill them again before going to the pool and severral times during the evening. most of the time we filled them with ice water as we drink alot of water, but unfortunately we also drank a good amount of iced tea and lemonade. it sure was cheaper than spending three something for each drink. the mugs saved us a ton. its great now that they will be included.
