There will be a hot meal in CE, a choice of two dishes (pending availability). The CHML will most likely be chicken nuggets, mash and peas/beans. If you don't order a special meal such as a CHML your 13yo will be offered what's on the regular menu.
In ET it'll be a deli box with a sandwich/wrap, cheese & biscuits and a pudding. No SPMLs available in this cabin.
