My family will be cruising on the Inner passage on June 24th. We will be bringing our boys, ages 9 & 11. Can anyone offer packing advice? I feel like the packing lists I'm finding are too general. I don't know if we should bring winter gear or not. What about footwear for shore excursions (hiking or rain boots)? Will we need shorts at all? Will it be warm enough to swim? Any general advise for a first time cruise with kids?
